The Chamber of Speech is mentioned several times in surviving histories of Kaleth, though only in passing. The scrolls Jedi Knight Do Zonn obtained suggest the chamber was a repository of knowledge in some form, and reference a mysterious being who was master of the chamber's lore.
Attempts to fully examine the old machines in the Chamber of Speech have proved fruitless, as the battle droids that guard the ruin are particularly violent. There is evidence that the droids were programmed to return to the chamber if its other defenses failed. Whatever secrets the chamber hides, the ancients of Kaleth were careful to protect them.
