After taking a peek around this website, I found a writeup for the dead power Aoskar that defines him thusly:
Aoskar (The Eternity Guide, The Lord of Portals, The Master of Infinite Expanse) Greater God of The Outlands
Portfolio: Belief Shaping, Enlightenment, Sigil, Planar Travel, Portals, The Rule of Three Alignment: Chaotic Good Domain Name: Sigil Worshipers: Planar Travellers, Magic Users, Sigilites Domains: Chaos, Knowledge, Protection, Travel, Trickery Symbol: A doughnut like circle. Favored Weapon: Quarterstaff
All fine and dandy, except I did not get the impression that Aoskar was a Knowledge-type of deity per say. That, and I found a Domain that might suit him much better. Who else remembers the Portal Domain from the Forgotten Realms setting?
So, maybe this would be appropriate...?
Aoskar (The Eternity Guide, The Lord of Portals, The Master of Infinite Expanse) Greater God of The Outlands
Portfolio: Belief Shaping, Enlightenment, Sigil, Planar Travel, Portals, The Rule of Three Alignment: Chaotic Good Domain Name: Sigil Worshipers: Planar Travellers, Magic Users, Sigilites Domains: Chaos, Portal, Protection, Travel, Trickery Symbol: A doughnut like circle. Favored Weapon: Quarterstaff
With that out of the way: is there any more information about Tomeri, the goddess of wisdom and love mentioned in the Planescape adventure Dead Gods? The article in the site's archives is barely a stub, and I have yet to find any other site that gives more info than the bare essentials of her portfolio and the name of her killer.
I'm pretty sure Aoskar was just a god of portals and planar travel. So his portfolio is way too wide (enlightenment? really?). And if he has the chaos domain he should also have the good domain.
Not that these are your fault, just making my thoughts on this writeup known.
Pants of the North!
