The Cuman quest is actually great.
-Settle things down at the tavern, avoid unnecessary bloodshed, tell townspeople not to be rash
-Go drinking with the Cumans, get to know them, learn about their past
-They are regular guys, they've been through struggles and hardship, they have hopes and dreams.
-We're not so different
-Learn some language, have some fun, hook up your new bro with a chick, go skinny dipping.
-Everyone passes out, sleep like a log
-Wake up before everyone else, murder them all in their sleep.
Only God forgives.
