Notes:

This is a shared task.

Aquarn wishes you to rescue a kedge from the hands of the Hadal named Silbek. To do so you'll need to disrupt their sacrificial ceremony by mixing the gems the priests use. Head into Rubak and kill "a priest" hadal until you get all 4 color gems, then go to the bottom floor to find Silbek and the 4 orbs. Give each gem to its opposite, red vs green and blue vs orange. After all four are done Silbek gets up, hail him, then go back to Aquarn to complete the task.
