Vampire God of Darkness and Hunger.

A statue of him resides in the Sacred Caverns of the Insectoid Hive.

Especially loved by Vampires and their infected thralls, Halik embodies an endless hunger, born from a time before the planes, when there was only a drifting, restless desire stalking the void. A single touch from Halik transforms mortals into new embodiments of this eternal craving, souls emptied of all but hunger. As Azema forges together pieces of every plane, Halik will ensure that his never-ending desire also has a home here. - DoU

A priest at the Temple of Ulos has you undergo a trial to determine your intentions, by placing a hand on a marble statue of Halik:

• Succeed, and earn his trust, as well as a gift.
• Fail, and he will leave you to your mission unaided.

Leaving an offering to the statue of Halik at the Sacred Caverns of the Insectoid Hive yields a chilling blessing;

You feel a deep and growing connection to the darkness beyond the planes and the unholy creatures who haunt the endless voidways of Halik’s domain. - The Hive (GS-ADV3)
