Khumash-Gor

Khumash-Gor was the most power warrior of all times in Pagan, his political conquest, which united Pagan, was even held by the Zealan Gods in the highest regard. But even he died one day, being only mortal, and to honor him, his tomb was built directly adject to the Shrine of the Ancient Ones. However, his spirit still was full of battle lust, and he guarded his tomb like a berserker, killing everyone who dared to enter and disturb his rest.

He found his final peace when the Avatar defeated his ghost to reclaim the Obelisk Tip from his tomb.
