Kristang was an Obsidian Dragon and a lower court member of the Ruby Court.
History
In 810 BR, Kristang visited the secret vault under the Northern Snowy Mountains which held a feral member of the extinct Ruby Court: Feredemius. In his rage, Feredemius tried to kill Kristang, only to be stopped by invaders from the future, bound to set right a long chain of events that almost destroyed all of Isonhound.
He was bound under the mountain to keep The Shadowfell voidal source alive, spilling darkness into Umbralhound.
(TODO: Some of this is conjecture, I'm not super sure of the details, need to cleanup Kristang info by using other page second-hand accounts)
