Palkar

Palkar is a young orc of the Frostwolf clan who serves as Drek'Thar's personal attendant.

Lord of the Clans
Ever since he was an orcling, he served as an attendant to the aging Frostwolf shaman Drek'Thar, who had been chieftain of the clan since the death of Durotan and the disappearance of Durotan's infant son, later known as Thrall. Just as Thrall would return one day and become Drek'Thar's student, Palkar was also trained in the ways of the shaman by Drek'Thar and became a shaman in his own right.

Shaman
Prior to the Shattering, Palkar escorted Drek'Thar to Mulgore to meet with Muln Earthfury, leader of the Earthen Ring. Drek'Thar threw a fit, but Palkar was able to calm him using herbs. He then carried him to Orgrimmar.

The Shattering: Prelude to Cataclysm
Palkar remained at Drek'Thar's side as the Frostwolf shaman grew ever older, and although it pained him to witness his mentor's slow decline, he had vowed to care for him until the venerable orc's last breath. As his master's memory failed, he largely dismissed Drek'Thar's visions as a sign of his increasing senility, and did not send word to Thrall of their import. Upon learning from Perith Stormhoof that the old shaman's vision that a peaceful gathering of night elf and tauren druids would be attacked had indeed come to pass, Palkar began to take his master's visions seriously again.
