Any bonus for retianing a Relic is a penalty for not keeping
At least one Dev/DM (Zing?) has expressed an interest in bonuses for keeping Relic, personaly I see it as a nice system which takes away the flavour of a Faction if they do not appease there patron god (via Relic)
Given the interests and likelihood of
something happening this system penailses those who have no jobs, high level charactors more so than low.
Hey, how about an inability to "Level Up" until to retrieve a relic, now that'd be hell nasty

(please its a joke don't even think about it)
