My empowering imm hasn't logged on in about a month and a half. There's no response to prayers, notes, or emails. So I'm stuck partially empowered, with no way I can see to actually have access to imm grantaed class features. Is there anything I can do as a player in this situation?

Typically characters who have had their imm go awol mid-run get some love from other imms if they have quality RP and positive impact on the game as a whole. Its not a perfect system but we also dont want to step on the toes of another imm and their religion/RP arcs if they haven't been able to cross paths with a follower for a little bit.
