Gilthares Firebough

Gilthares Firebough was a level 17 quest giver located in Northwatch Hold in the Horde-aligned territory of The Barrens. He was a deckhand on a moonshine transport between Ratchet and Booty Bay. The ship was sunk by Theramore zealots and Firebough, the only survivor, was captured and imprisoned in a tower at Northwatch Hold. He appeared to be affiliated with an organization known as the Thalo'dan Privateers. He was towards the Horde and the Alliance, although once the escort quest was started he became  to the Alliance—Thus allowing Alliance players to attack and kill him.

Gilthares has been missing since the Cataclysm - he could have been killed by the Alliance encroaching on the Merchant Coast, or he could have returned to the Eastern Kingdoms to officially join the blood elves. The truth may never be known.

Race
It is interesting to note that, though apparently a high elf and not a blood elf, he wore an abundance of red, which is a practice usually avoided by high elves. The reason for this may have been because he was not a part of the Alliance, and therefore was not afraid of wearing red clothes. He also expressed open hostility to the Alliance due to his enslavement.

However, before the Burning Crusade his old model was the commonly associated model with the blood elves, so we could think that his second model was wrong and this NPC was actually a blood elf (as in the case of Astromancer Darnarian), although the same model is now used by Quel'dorei Wraiths, which are high elf ghosts in the Ghostlands.
