Where is the Death Test located in Ardonirane?

[JimmyPlenty]

I see that it says on pg. 50 of Ardonirane, that the Death Test is under the Manticore Keep. But where is the keep? Where is the main entrance?

Only entrance I can see is in the palace of the Thorz on pg. 49 section D.

The Thorsz's palace is described on Ardonirane p.48 as a hexagonal keep of red stone, a.k.a. the Tower of the Manticore. The same page also shows location D in the palace, which is described on the following page as having a stairway leading to the Death Test. I suggest that "Manticore Keep" should have read "Tower of the Manticore".
