A Warforge invitation is given to the player automatically once they reach level 76 Archaeology. It is an invitation to the Warforge Dig Site from Zanik.
My dearest Player,
I am not surprised to see you have rapidly climbed the
ranks of the Archaeology Guild and, as it happens, I have
been put in charge of a team at the Warforge Dig Site,
south-west of the Feldip Hills. I would love for us to
discover the purpose of this place together.
PS - yes it is really me; it is weird, I know
