The seat is invited and not yet confirmed. Grand Marshal is the PvP title last held on the Hakkar server before The Burning Crusade (January 16, 2007). That honor belongs to the older war. It is not a rank on World of Warcraft: Forever.
Played a Night Elf Hunter.
A vanilla clip from 2006 still names Asinine against Nookie on Hakkar. Players from that server still say Asinine and Fifi were the two hunters pushing Grand Marshal, and that rogues quit Warsong Gulch rather than face them.
If this name is yours, claim the invite below. The claim is sent to the guild.
