The ruins are divided into Anutwyll and Anutwyll Inner Chambers, with various creatures on the first floor and one Troll inside the Inner Chambers. There is a secret room activated by pressing a button that contains a Varla Stone. In one of the large rooms there is a gas trap where walls come up and a large gasflow emits from the floor.
In Anutwyll Inner Chambers there is another secret room that holds randomly generated leveled loot. Inside is also a gas trap.
