I agree with Teraswaearto. In every MP game I have been in, someone on the verge of defeat has given gems to allies or enemies of an enemy. Never once has anyone asked that the gems be distributed amongst players.
If a sub is found for Ermor, I think it would be nice for the benefiting nations to give the gems to the new player, but certainly not required.
Ultimately, I think this is up to Agartha and Abysia.
My notion was just that the Ermor position was being sabotaged . When it comes right down to it, I really don't have a strong opinion on the question, but since it looks like we have a sub for Ermor, he should have a voice on this.
