It is Armagan's quest from the original Mount and Blade...it's always amazed me that quests do not lead to great rewards of money or weapons or armour. I mean, isn't that the whole point of a fantasy medieval quest? No what do we get, some RAW MEAT!
Is it this hard to make something compelling? Do this hard quest, get a cool shiny sword! Rescue a princess, get married. I dunno, there;s plenty of better ways to do quests. Whoever comes up with this sheep herding stuff must have the lamest imagination ever.
