adventure mode, investigating an * on the world map, i came across a group of 3-4 "death stalkers" (human and dwarven soldiers, armed), a single human lasher "grave one", and a single corpse. i guess "death stalker" and "grave one" are autogen'd necro cult positions or something? they [l]ooked like normal humans and dwarves
i dropped out of travel mode before they could ambush me, and we ended up within line of sight of one another, but not hostile. i greeted one of the humans, and their whole gang immediately turned invisible (except the corpse) and started beating the shit out of each other. i hung around watching the combat announcements, and eventually the last two(?) turned on me and horsey. i tried to leg it, but they got one of lorbam's hooves and she couldn't move faster than dwarf speed, so i tried to hop off and sprint for it, but it turned out i'd already taken a leg hit too, so i scrambled for a bit and then the lasher got me in the head and that was the end of that
anyway, it was weird that a) they weren't hostile immediately, unlike an ambush? and b) they turned on each other first?
combat log, in case it's useful somehow (expires in 180 days)reviewing the log, they were still on each other when they started attacking us, so i guess it was just a free-for-all and when it rolled over to us, we started copping it too
