There is a note there you can find saying that the statues lie, or you can mindread Keara to find that out...
The solution is:
The statue at the start is Devastation. In the fire room, the statue on the west wall is Mayhem, while the one on the south is Havoc. In the green room, the western statue is Waste, while the eastern one is Chaos.
Or see the spoilers immediately above your post to see how to figure it out.
