Thought I'd tell a story to spark this, and see what madness Valheim has brought you.
My buddy and I are late-era Mountains, venturing into the plains before Fuling raids become a thing. We're scouting and opt to start fighting a small village that doesn't have Berserkers. Well, we get too close to a couple Lox, so there are 6+ Fulings and a couple Lox, and the occasional Greydwarf from the nearby Black Forest for good measure. Then a freaking Troll comes in, and… starts fighting the Lox. He practically saved us from having to fight both Lox and the Fulings in close proximity.
Well, we manage to fight them off a bit and kill the Fulings, the Troll isn't a big threat to the Lox and has died, and then we see "You Are Being Hunted". Wolf after Wolf piling in. But… after a minute of fighting them off, we see them fighting the Lox, too. Start trying to put the Lox between us so they fight, which works as intended. Wolves won't win, but they do cause damage.
Madness. Chains of nasty-seeming events. But when we saw the Troll and Wolves aggro the Lox, it was brilliant.
