Gzemnid

Gzemnid was the beholder god of gases, fogs, obscurement and deception in the Underdark.

Description
Gzemind appeared as an oversized beholder (about in diameter) of sky-blue coloration. Atop his head was a crown-like circle of long tentacle-fronds, extra appendages dexterous enough to use rods and wands.

Personality
Gzemnid was a subtler, more secretive god than the tyrannical Great Mother, a highly intelligent deity whose thought patterns, unlike his predecessor, were actually coherent, if chaotic. The wily Gas Giant was also less aggressive than most beholders and, again unlike the Great Mother, was prepared to parley and bargain to add to his store of knowledge and magic. Of course, he would prefer to simply take what he wanted by force but might negotiate if his targets were obviously powerful and not immediately violent themselves (using his magical rod for leverage in the bartering).

Possessions
Like the Great Mother, Gzemnid kept a cache of magical treasure and lore somewhere in the Outlands. Avatars of Gzemnid carried a rod of beguiling in their tentacles.
