When logging in between May 25th to August 1st you will recieve a main hand weapon transmog and a shield/staff transmog (depends which faction, horde gets staff alliance gets shield).
Alliance-
Shield: http://legion.wowhead.com/item=141000/replica-lions-heart
Sword: http://legion.wowhead.com/item=140999/replica-lions-fang
Horde-
Axe: http://legion.wowhead.com/item=141001/replica-blood-guards-cleaver
Staff: http://legion.wowhead.com/item=141002/replica-staff-of-guldan
If you are going to try and do a faction switch to get ally on horde and horde on ally I advise you to mog to the thing you want it on before you transfer or it will most likely turn to the other factions weapons when you switch over.
