This quest is available after accepting Keira's offer to help find a magic lamp at the end of Wandering in the Dark.
1. Light fire on statue directly to the right of the arched doorway
2. Light fire to the left of the arched doorway.
3. Light fire on the far right of the arched doorway
4. Light fire on the far left of the arched doorway
CAUTION: Every time you light the wrong fire you will have to battle one or two wraiths. GAMER TIP: There is a bonus passage way with a good amount of loot but it is guarded by a golem. Locate the lamp first before exploring this section so Keira helps you in the fight. Might want to go back to the place of power tome to boost Geralt's Yrden sign effect too since it helps slow the Golem down.
