As it happens I can trade both earth and nature gems in decent volume and could definitely use both death and water gems. I am still woefully behind after the attempted early ganking by both Mictlan and Arco so am thankful for any small favors that help me catch up to everybody else.
I would also like to thank Arco for volunteering to be my first avenue of expansion after I lost out on the chance to grab my share of indies.
We Agarthans are generally peaceful and reclusive so feel free to offer to negotiate a truce and try your barbaric expansionism elsewhere.
There are other options than instant victory or quitting in a game with lots of diplomacy.
