Agashem

Agashem appears to be a leader among the Grimtotem tribe of tauren, as he or she is the one who orders them to destroy the Shady Rest Inn.

You find this out by reading the  [Grimtotem Battle Plan].

However, Agashem could simply be an near-anagram of "Magasha," which is suspiciously close to "Magatha," the leader of the Grimtotem.
