In Terms of the Heroes
Tin is Saren's brother. The heroes attempted to rescue Tin on Umbara but failed, and followed him to Katarr, but were unable to prevent him from being transformed into an abomination. The heroes ran from Tin after killing Darth Homunculus and finding Tin to be too tough for the little resources they had left.
