Ten Bitterrage

Ten Bitterrage is a pandaren found at the Elders' Path on the Wandering Isle.

Speculation
His presence is strange, for despite being the only pandaren wearing armor of the zone, he doesn't have any dialogs or role to play. It is not known if he's at the base of the path to warn young pandaren not to go any further or if he was a challenger not found worthy to enter the Wood of Staves.
