Warpweaver Hashom - "A WoW Rehash/Revamp"
Additionally, Thalmor has proposed the following:
Thaumaturge Vashreen - "Have a true gamers hunt"
Vaultkeeper Razhid - "hide a true leak" with remaining letters ZPRV.
ZPRV shifted to the right by one letter is SW/AQ (Stormwind Ahn'Qiraj)
Numerically, SWAQ is 1,17,19,23 and 1+19 = 20 and 17+23 = 40, add this to the AQ and you get AQ20/40
SW could refer to Stormwind (where the screenshot is likely to be taken), or perhaps Sunwell
Sneaky Blizzard?
edit: meant to write "Warpweaver Hashom" (ignore first few comments below)
edit: added Snicksnack's excellent hypothesis
edit: attributed hypothesis to Thalmor instead of Snicksnack, added some more info
