It's difficult to say. E-Rep is centered in New York and the Votanis Collective is in Brazil so the two have mostly avoided stepping on each other's toes too much. With both groups gathering more territory there's no telling how long that will last, however. And the problem with trying to negotiate with the Votans is that they consist of seven different races, each with their own interests and moral code. So, for example, the Indogenes are cold, but they can be reasoned with and would probably accept a logical argument for peace if you can give them one. The Castithans, however, are a male dominated society of egotists who fear being seen as weak and loathe the idea of surrender.
