Azjol

Azjol, the Spider King, is a dark ascended being and a Demonlord. He represents trickery and deception, and his powers relate to this.
Azjol is a powerful creature who leads a vast group of followers known as the Cvaldin, and rules his own section of the Divine Realm; an area known as the Endless Web.
Azjol was formerly the King of Violetholt, but when he attempted ascension the gods cursed him with such a horrific appearance that he could no longer live on the surface. He lead a loyal group of followers underground, and now rules the Depthers.
Azjol is not a true ascended. He is immortal, but his power is a twisted corruption on the divine magic of the gods. The gods do not willingly grant him power, so he must constantly steal it from them through rituals.
=== Background ===
Azjol stole the throne of Violetholt through a grand deception, killing the true prince and replacing him. As king, he was renowned for deception and trickery, and was a powerful dark priest. Like many in Violetholt, he worshiped the Faceless God, though he constantly tried to come up with ways to trick the gods and steal their power. For this reason, he was the Faceless God's favoured disciple.
Azjol gathered his followers together to perform a great ritual, promising them that it would grant them all immeasurable power. In truth, the ritual would drain the power and energy from them all, and imbue Azjol with it, allowing him to ascend. At the completion of the ritual, the gathered mages began to wither and collapse, and Azjol was imbued with great power. That was when the Faceless God approached him and offered to make Azjol his champion.
Azjol had been expecting this, and activated a secondary ritual designed to steal the god's power. But it is hard to trick the god of tricksters, and the god manipulated one of the still-living withered mages to sabotage the ritual. With the ritual sabotaged, Azjol was at the god's mercy. The Faceless God cursed Azjol with a horrific appearance, that of a monstrous spider creature.
At the ritual's completion, Azjol had become an immortal monster, but lacked the power of an ascended that he desired. The mages who survived the draining had become withered and hideous, and now fears Azjol more than ever before. With these followers, Azjol descended into the caverns below Violetholt, to regather his strength.
With his followers, Azjol performed a ritual to create his own private part of the Divine Realm, which he could use to steal divine powers. This area became known as the Endless Web.
