Among the many planes of D&D 5e, in what part of what realm, might what aspects of Zorquan remain?
Way back in D&D 2e,
Cult of the Dragon listed Zorquan as a neutral draconic deity, largely unconcerned with individuals.
The Draconomicon stated that Zorquan decried the zealotous bloodshed of the Draconic Holy Wars.
I gather that Zorquan's followers were urged only that dragons should each be true to their own nature. Zorquan seemingly had no diametrically opposed enemies, but Sammaster & anyone who would enslave dragons or destroy all dragons, might have been the most likely to ire the ancient dragon. (?)
It appears Zorquan's primary demesnes were reputed to be on the Material Plane, and a neutral plane in the Outlands.
I've read in some sources, of theories which claim draconic deities were not "true" Gods: Instead, it is believed some "mortal" dragons gained contact with Aspects of themselves from other planes; merging, in something akin to apotheosis. However as of 5th edition, Bahamut, Tiamat, & Io, seem to be confirmed as actual Gods, presumably with all the conditionals that entails. (?)
Sounds like Ao assigns domains on Toril, though I've no idea the criteria...
Dating from the years -30,000 to -24,000 DR, Zorquan was counted as a Greatest Wyrm, a High One, & either an Intermediate or a Greater Deity "of dragonness", depending whom you asked.
In 5e, there's nothing published about Zorquan, so far.
One might presume Zorquan died, either toward the end of the Draconic Holy Wars, or thereafter. However, I find no direct indication of this.
In 5e, the mind of a god apparently leaves a corpse in the Astral plane (with potential regional effects).
Speaking purely in terms of RAW or RAI, would Zorquan be likely to have a corpse in the Astral?
(potentially with Zorquan's memories\thoughts taking tangible forms, there)
Alternatively, might Zorquan still live, somehow?
If Zorquan lives, where?
If not, what (if anything) is left?
