If this game is Gems of War, does that mean all gems in the game belong to War???
If you mean war as an activity, and not as an anthropomorphic personification, then yes. Otherwise, no.
I think the OP is on to something! That must be why I never see War on anyone’s teams - he’s too busy counting gems and possibly swimming in them like Scrooge McDuck. Certainly not because it’s really hard to design a team around him…
Now that is what I call Gems of War!!!
