Chamber of Echoes

Presently, the Chamber of Echoes is a closely guarded secret between Iovaerix and those he's deemed trustworthy of knowing it exists. With the chamber's importance to the realms and the fight against Hyltades, ensuring nefarious forces do not gain access to it is paramount.
Constructed in an ancient era by the late Gaulnym Thryn'tostynn as a gift for Sardior, this chamber is a massive cave structure carved out from deep beneath the surface of Chromatia. The chamber itself was woven together with various jewels, metals, and other precious materials commonly associated with dragonkind and tuned to the Dragonsong, which originates from somewhere deep inside Chromatia's core. 
The chamber itself is large enough to fit as large a creature as an ancient dragon, but its intent was actually aimed at wyrmlings and young dragons who wished to train their echosight, permitting them to commune with their draconic echoes elsewhere in Realmspace (Material Plane), for better or worse. While few dragons today inherently gain the gift of echo sight, the chamber still serves its original purpose - heightening an individual's ability to hear the Dragonsong and connect with their echoes, an effect most helpful in finding the Severed Echoes created by Hyltades. 
A physical entrance to the chamber is located far above, in the Praetorium's basement. However, arcane gates connecting to key landmarks throughout the world and beyond exist, permitting creatures to come and go from the Chamber of Echoes freely. The chamber is guarded by Solari and Lunara, echoes of the Chromanexus's eldest solar and lunar dragons, whose starry eyes can see the truth and history of anything that wishes to gain entry and will deny passage to those they perceive as a threat to the Dragonsong.
