Apsu

A good dragon deity. Apsu is well-known amongst dragons, but isn't widely followed by other species as dragons tend to be misunderstood as destructive. He also generally does not interfere with the world or reply/reward his followers.
Apsu is in the middle of a great war with his arch-enemy, Dahak. Pharasma sends some of those who pass on to fight alongside him.
Apsu and Dahak once worked together to imprison Rovagug.
Chief Sootscale believes the best way to worship Apsu is to store valuables in one location, like a dragon's hoard.
Eranex suggests that the best way to worship Apsu is to do things a good dragon would do, defend those in need without the promise of reward.

The Dragonic Apsu

The Dragonic Apsu is an enormous epic about Apsu. Its first 9 lines are its most famous:

I shall then be Apsu,
for I am the first.
I am the primeval,
who was of Heaven
and of Material
before they had names,
for I created them with Chaos.
I then shall go
and I shall end Death
