Just some stray thoughts. I don't know if they have been recorded elsewhere.
I am convinced Xau-Tak is an Elder God. In the first livestream showing off the Temple of Aminishi, one of the developers stated the storyline is not about "Gielinor's elder gods."
The words "Xau" and "Tak" are both single-syllable three letter names, in line with the other elder god names. Perhaps Xau-Tak is some kind of fusion of two elder gods. We know that elder gods lay eggs and die when they hatch, but perhaps Xau didn't let go when Tak hatched (or vice versa). Azzanadra's dialogue implies Wen might be going through a similar thing because she is known to be in two locations.
Xau-Tak also appears to exist outside of time and can break the fourth wall, which are powerful traits we haven't seen from any of the younger gods. Kranon's journal implies Xau-Tak had a presence in the previous revision, making him older than any of the known younger gods.
Xau-Tak's association with oceans is also in line with the elder gods' associations with geography, like Jas with deserts, Wen with ice, Ful with volcanoes, etc.
Sound and music seems to be important to the elder gods, as well as Xau-Tak. We saw a glimpse of the "Elder Choir" in Sliske's Endgame. Black Stone is known to sing, and can be activated by the "dissonance chorus," as mentioned in the Redacted Dragonkin Research.
The notes also mention that black stone can cancel anima, so maybe Xau-Tak is some kind of "anti-elder god" who feeds off of the black stone instead of anima. Perhaps this is related to how the known elder gods are female, whilst Xau-Tak is male.
The Obsidian Tribunal seems to be related to Xau-Tak, as we saw in the Shadow Reef. Obsidian is a black stone.
I don't think Xau-Tak is Mur, the bloated parasite of Renmark. I think Mur is another dead elder god.
