 * Join Doomsday Cult

Description
It's getting difficult to keep the cultists out of the public eye and rumors are spreading across the city. I want you to join the cult and learn as much as you can.

Approach one of the doomsayers in Old Town and tell them you wish to join their group. The doomsayer will likely give you clothing and instructions to meet with other cultists in one of the group's hideouts. It's the only way to gain their confidence.

Rewards
You will receive: (at 80)

Completion
