Frostfloe Deep[62, 42]
is a large cave in the Storm Peaks region, located northwest of Camp Tunka'lo. Since ancient times it has been used as a burial place for Taunka warriors and chieftains, and contains many Taunka relics.
Recently, it has been corrupted by a malevolent force that seeks to rewrite the history of the Taunka, sending raging elementals into the once peaceful caverns. The immortal sends you to Frostfloe Deep to question the spirit of Chieftain Swiftspear about  in an attempt to determine what is happening there.
