Neutral Ground for the gods

Quick question: Is there some neutral meeting place where the gods hang out in canon?

I plan to frame my next game as something like The Odyssey, with the gods actively watching the PCs adventures and messing with them or giving them favor. Given this, I want a place where the gods of different and opposing alignments can hang out and chill and play this game with mortals, without a risk of the gods fighting themselves.

I have to feel like the Boneyard is able to accommodate whatever beings are willing to abide by its rules, and is also the true neutral plane. There are whole divine realms in the spire, so I don't know why it couldn't also hold the conference room to end all conference rooms.

Nivi’s affinity for earth and caves is reflected in her home on the Plane of Earth, but she is unusual among the gods for not maintaining a stable divine realm of her own— though some rumors claim she lost hers in a bet. Instead, Nivi tends to set up temporary residence in massive, jewel-studded caverns deep within the Eternal Delve or on the Material Plane. Nivi has few enemies, and she occasionally agrees to serve as a neutral arbiter between powerful entities who wish to meet and parlay, though all visitors to any of Nivi’s abodes are required to play at least one game of chance before conducting any other business.

Might be useful information for your purposes.

There is indeed no widely recognized place of meeting for deities in the setting.
Now, Nivi's abode seems like a perfect place for some deities to play at a game of chance that involves a few mortals.

Rahadoum was also mentioned a while back as being a place of parley between the gods and their emissaries, ironically, because the gods don't have any competent minions there to play intrigue with. :p

But alas! Everybody seems to have forgotten dear Alseta, our patron lady of doorways and communities. From Inner Sea Faiths:

"Known as the Argent Gate, Alseta’s realm is an ornate gate and adjoining temple located on a massive piece of solid silver floating through the Astral Plane. Some speculate that it was once a part of the Eternal City of Axis, but that Alseta moved it to avoid making gods of other alignments uncomfortable. Regardless, the Argent Gate is a powerful artifact capable of creating portals to almost anywhere in the Great Beyond. Combined with its location on the neutral ground of the Astral Plane, this makes the Argent Gate an ideal location for meetings of the gods."

"Praise Alseta the
opener! May she
open the path to
virtue and wisdom.
Praise Alseta the
closer! May she
close the path of
iniquity and strife."

Astral Plane could probably work for it, the deities could probably transform areas of it into a temporary amphitheater for watching things unfold
