[@Hillan]There will be specific events for PVE (and possibly PVP in the future with tournaments). However, players are free to PVP if there's a story-related reason. Some characters may be hot-heads, may challenge another character outright (maybe heard that character was strong say if said character had a reputation), or there could be a misunderstanding, etc. Whatever reason you guys come up with. If they're already acquainted, then there's sparring.
