We recognise that, generally speaking, adventures are most enjoyable for players and monsters alike when a party works together for the sake of achieving a common goal, despite natural differences that will occur.
In addition, Animus is not designed to facilitate player vs player combat.
As such, we encourage participants to handle PVP through social conflict, political maneuvering, and snark, which are supported by the setting.
However, sometimes the most appropriate thing for a player to do is to respond to an IC event with violence against another player. This kind of action is entirely acceptable.
We would ask, however, that our players are careful to not generate characters specifically with the goal of PVP combat in mind, and, furthermore, if they do seek to participate in PVP, to find participants who would enthusiastically enjoy the prospect rather than players who dislike it.
When putting together the player party for an adventure, including characters between whom PVP is inevitable will be avoided as much as is possible.
