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 Gnome Mage.
Level 60 PvP footage still names Ayrll a mage on Hakkar, and the reupload calls that mage one of the best known on the server. A vanilla player still names that gnome mage Grand Marshal in the top PvP guild, and says the videos were big there.
If this name is yours, claim the invite below. The claim is sent to the guild.
