The Chamber of Daegon is located at the core of the Red Dragon Caverns in Earthrealm.
Overview
In this chamber at the heart of the caverns is where the Red Dragon Caro was tasked with guarding Daegon during his hibernation. After killing his parents for their so called deceit, Daegon then imprisoned his guardian and forces him to transport his clan anywhere in the realms.
Taven came to set his old friend free after he fought Reptile. Caro told Taven why he's in chains and what happened to Daegon. Caro then opened a portal for Taven to go find his brother in the Netherrealm and to make him pay for what he has done.
Caro who was last seen, stay left behind atoning for his mistakes by destroying the rest of Daegon's precious clan and their headquarters for the disgusting atrocities they committed in his own name. His final fate was uncertain.
