When you accepted this quest to steal an orc horde’s loot, you’d honestly figured that the townsfolk had been exaggerating about the numbers. Sure, you thought. They probably think an orc horde is only a handful of the little buggers. Nope. Turns out that when townsfolk say a horde, they mean at least sixty.
Really, they should have called it an army.
Oh well. The best plan you can manage with this bit of news is to disguise yourself as an orc and join the ranks--just until you can get your hands on the treasure, in any case. That is assuming no one realizes the face you are using isn’t originally your own.
