Galar'thus Rivertree

SS Suramar

Galar'thus Rivertree was a member of the Moon Guard during the War of the Ancients up until the third invasion.

War of the Ancients
Galar'thus mentioned to Malfurion Stormrage that he had seen his brother Illidan walking by himself into the area where Deathwing had earlier attacked both the Burning Legion and Kaldorei Resistance.

Legion
He survived until the third invasion of the Burning Legion, where he was killed by the nightborne. An adventurer of the Alliance and Horde performed a rite for him.

Thalrenus Rivertree, a surviving member of the modern Moon Guard, is presumably his descendant.
