Rawal came by Jaern, having found an ancient laboratory in the Whitespires.
He recruited our adventurers into exploring.

Doors were broken down, enemies were defeated, loot was acquired.
Lavare willingly decided to enter a mysterious inky black pool, which the adventurers had previously determined restricted communications and light, and was never seen again. The pool returned a variant form of him.

They uncovered some secrets, gaining deeper information about the world, ultimately returning to Rawal and being paid.
