Why no words 'Æsir' or 'Vanir' in OL?

[Nordic]

Wodin (Odin) is a major figure in Æsir and Asynjor god pantheon. Vanir gods Freyr (Wralda) and Freya (Frya) are directly tied to that pantheon:

Freyr er hinn ágætasti af ásum.
Freyr is the most renowned of the Æsir [source]

kölluðu hann veraldar goð
called him the god of this world [source]

ÉR THÉRE ÀRGE TID KÉM. WAS VS LAND THÀT SKÉNNESTE IN WRALDA.
Before the bad times came, our land was the most beautiful in Wralda
[here Wralda = world, source OL 047].

The OL Frisians deal extensively both in peace and war with the upper class of Finns, with the Magyars (Magis) and Magus being good match with the seer class of Finns and the leading figure of Väinämöinen the sage and judge. Furthermore the two tiered Finnish class system is a very good match with Bock family saga (aka Väinämöinen's mythology by another name) Finns who are divided into the Aser (Æsir) upper class with titles like 'Väinämöinen', 'magician' etc and the lower class of Finns called Vaner (Vanir) after them being 'only', 'just', 'mere' ordinary people (vaan, vain in Finnish, cf. OL 051 "All other [Finnish] folk count for nothing").

The OL mentions the Germanic-Frisian presence in the Italian peninsula:

THA HÉINDA KRÉKA.LANDA HÀVON VS TOFARA ALLÉNA TO HÉRATH. MEN SUNT VNHÜGLIKA TIDUM HÀVON RA THÉR ÁK
ÀFTER.KVMANDA FON LYDA ÀND FON FINDA NITHER SET.
The Near Greeklands used to belong only to us, but since time immemorial, descendants of Lyda and Finda have also settled there. [source OL 199]

The old Italian gods were known as Aiser i.e. same as Æsir/Aser above.

The old Frisian judges were called Asega after the Æsir judges we can read from Ynglingasaga ch. 2. They even had a Asega-book.

That Oera Linda book is a real deal is certain. But why there are no words 'Æsir' or 'Vanir' in it? Was the role of a deity reserved solely for the Freyr-Wralda as cosmic deity (OL 035: "I only know one ‘god’ — that is Wralda’s spirit")? Did the Finns and Old Italians leave a bad taste for the Aser/Aiser term? Was Wodin's foolishness so bad experience that no true Frisian wanted to associate with Æsir faith of Odinism (unlike e.g. Vikings)? Is the Asega a term used by the Norse and Finnish oriented Frisians, with them commented negatively in the OL narrative – what gives?

The term (A.SEGA.ÁSKAR) is explained in the OL as being "asker", or "advocate."

[195] THÉRVMBE WIL IK THÀT FORMA VR SWARTE A.DEL SKRIVA. [195] So, first I will write about Black Adel. SWARTE A.DEL WÉRE THENE FJURDE KENING AFTER FRÍSO. BY SIN JÜGED HETHER TO TEX.LAND LÉRED.

In his youth, he had studied at Texland, and later on at Staveren, and then he traveled widely throughout all the states.

When he was twenty-four his father had him elected law speaker and ‘asker’. From the moment he was made asker, he would always advocate for the benefit of the poor. THA RIKA.

ALSA ÀRG IS.T KVMEN THAT SIN TÁT HIM NÉI THA ÁGUM SACH. For reasons such as this, he was considered the friend of the poor and the scourge of the rich. It became so bad that even his father shied away from him. THÁ SIN TÁT FALLEN WAS ÀND HY VPPA THAMHIS SÉTEL KLÍWED. THÁ WILD.ER [20] ÉVIN GOD SIN AMBT BIHALDA.

The rich objected to that, but the masses supported him and the rich were lucky to escape unharmed from the assembly.

(Page 213).

Whether or not the æsr are the same as A.sega I won't say for sure, but it was an elected office, at least in the OL.

A note on Asega: this word in OL is split as A.SEGA, elsewhere É.SEZA, so the word literally means 'to speak right/even/waterlike/just'.

4g. Crete [039/20]
THACH THÁ THA FORSTA SAGON THÀT HJA HJARA RIK VRLJASA [25] SKOLDA THÁ JÉVON HJA THÀT FOLK FRYDOM ÀND KÉMON TO MY VMBEN É.SEZA.BOK.
But when the princes saw that they were about to lose their dominion, they granted their folk freedom and came to ask me for a book of laws.

I think the word 'Vanir' (Dutch: 'Wanen') derives from Fryas:

1. verb WÁNA: (falsely) believe
MIN.ACHTJA NACH WÁNA
ELK FORST WÁNDE FORTH
HJARA SELVA DROCHTNE WÁNE
EN LÍTH DÉL THÉR WÁNDE

JY ALLE WÁNATH
IK SKOLDE [10] WANA
NV SKOLDE ÀJDER WANA

2. noun WÁN: illusion
NAVT INNA WÁN

3. WAN as part of compound word (vain, pseudo-, corrupted):
WANKÉTHINGA
WANHAVEN (?)
WAN.WÍSA
WAN.SINNICH
WAN.SPRÉKE
WAN.FRÍAS/WAN.FRYA.S

As for 'Æser' (Dutch: 'Asen'), I suppose a relation to the word for 'east': ÁST.

Or perhaps verb ÁSA (Dutch: 'azen')?
TO THA LESTA SKIL THAT FENINIGE [20] KWIK THÉR VP ÁSA ÀND THÉROF STERVA.
In the end, the toxic vermin shall feast upon it and perish.

I wonder if the 'ace' of playing cards (Dutch: 'aas') might be related.

[Nordic]

I think the word 'Vanir' (Dutch: 'Wanen') derives from Fryas:
1. verb WÁNA: (falsely) believe [...] 2. noun WÁN: illusion [...] 3. WAN as part of compound word (vain, pseudo-, corrupted)

Wiktionary's English vain fits here, but for some doesn't mention the connection to the Dutch word wanen – a clear error at Wiktionary. Finnish vainaja 'dead person', ventovieras 'unknown guest', 'alien' are similar (OL 051 on Finns: IS NUL IN.T SIFFER ‘is null in the cipher’).

[pirus]

I thought at one point that 'east" as cognate to 'aesir' was interesting. At the moment I gravitate more to the mainstream explanation of the IE meaning of the word as in Sanskrit 'noble'.

aes- would coincide with eer/ Ehr (Dutch/German for "honor") ('s' = 'r'). Also already claimed by philologist in 19th century.

Although correct of you Nordic to say that this term is not used as such in the OL.

Always found the Bock Saga explanation much richer in this regard.

[Nordic]

The term (A.SEGA.ÁSKAR) is explained in the OL as being "asker", or "advocate." [...] Whether or not the æsr are the same as A.sega I won't say for sure, but it was an elected office, at least in the OL.

A note on Asega: this word in OL is split as A.SEGA, elsewhere É.SEZA, so the word literally means 'to speak right/even/waterlike/just'.

In the Finnish Magus system, as detailed extensively in likes of the Bock family saga, a major job of the Aser king (Æsir king) is to be part of a ritualistic asking system where the main religious and philosophical value leader is called Ukko Väinämöinen with the latter's name referring to the water via väinä 'streampool'.

I can confirm the explantion given in the linked video by late American re-teller (d. 2020) is accurate as to the source story. While the video deals with mythical paradise age narrative, the exact same asking system understood in the same source story to have been in use up until 1050, when it broke down due to foreign Christian armies and the characters relocated to northern Finland (Kainuu region) and nearby Lappland up until their surrendering to a Christian king in 1248. The seven islands and Valhalla story is the same core story as seven islands and Walhallagara in OL, just localised into Gulf of Finland instead of Walcheren island in Holland (OL 005: "Foppo, man of Dunros, reeve of the Seven Islands, was sea king five times. The burg Walhallagara is under his care"). A major difference between the OL Frisian party and most of the other northern Europeans was the issue of power, with perhaps the Icelandic Norse reminding somewhat of the Frisians.

This kind of oracle giving advice to askers is present in OL narrative via Minerva Nyhellenia, who famously is accomppanied by her office holder regalia and is met by high level guest seeking answers on various questions:

When Nyhellenia, whose own name was Minerva, was well established in the land, and the Greeks loved her almost as much as her own folk, there came to the burg a group of princes and priests and asked Minerva where her ‘erva’ (inheritance) lay. [...] Once they came and asked: “So if you are not a sorceress, what then is the purpose of the eggs you always have with you?” [...] The priests replied: “Well said, but what of the hound at your right hand?” [...] “That makes sense indeed,” said the priests, “but tell us, [035] what is the meaning of the night owl that is always sitting on your head? Might that light-shunning animal be the sign of your clairvoyance?
[source: OL 033-035]

To my mind this all suggests a formal sagess office in the burg castle.

In this recent german docu on Oera Linda it is mentioned that on Helgoland(Heilige/Holyland) there was the "fosite-cult' and implies this may be remnants of the Festa origins. This is among other things what Wikipedia says;
Fosite (from Frisian 'Fosite saga') or Forseti. Male Norse deity of justice, possibly cognate to dutch 'voorzitter'(president). Possibly from Poseidon or scottisch-gaelic Fearsithe(peacemaker) is the Mars Tingsus(God of the Ting) according to inscriptions in England about Frisian mercinairies. Some claim Forseti was one of the 12 Asega's.

(quoting wikipedia:)
Fosite (from Frisian 'Fosite saga') or Forseti male Norse deity of justice possibly cognate to dutch 'voorzitter'(president).

Oera Linda confirms that 'sitting in front' was something related to honor, in at least these three fragments:

E-23.07 — Laws/ Mother and Kings at War
there must always be three burg lords of the Mother present, sitting in front (FÔR-ANA SITTA)

E-25.04 — Laws/ Security and War Aftermath
At feasts, they must sit in the front (FOR ÁNA TO SITTANA) so that the youth may honor them.

F-27.12 — Minno’s Writings/ Laws for the Seafarers
They must also sit in the front (FÔRANA SITTA) at public feasts, at domestic feasts — indeed, at all feasts.

FÔRANA may also be related to FRÁN (pious, devout; Dutch/German: vroom/fromm).
