On the Origins of the Five half-orcish brothers...
Life had not been easy. It was bad enough being brought up in a damp, dirty dungeon and coping with rats all day, but having an orc as a father was almost too much to handle. Dad was not nice; he smelt bad and his table manners were disgusting. With half-eaten food dribbling down his chin he would take his BIG NAILED STICK and beat you all for no apparent reason.
Dad at mealtime. May he rest in pieces
Then, Grukyt Mange Eye and his mates arrived...
They bust into your lair and killed your father before he even had a chance to grab his axe. Fearing for your lives, you hid under the table and hoped they wouldn't discover you. Grukyt found you all the same, but instead of killing you, he adopted you as his own.
Things improved a bit then. Instead of living in a dungeon you had the luxury of Grukyt's damp and cold cellar, with lots of bugs and spiders to feast upon. Grukyt proved a kind foster parent, he only beat you with a small stick that didn't have an nails, and ensured you had a good education in the thieving arts. He even sent two of you to Harik the Hatchet to learn how to fight and, being a religious man, Grukyt insisted that one of you should follow the Dark Path and become a cleric. An unhappy childhood turned into an enjoyable adolescence as Grukyt took you on many daring robberies.
And tonight...is going to be the night of your greatest thieving achievement yet.
Curious Note: The Half-orc PCs on this adventure are not among the usual 10% of human/orc hybrids that can pass for human or mostly so and form the bulk of regular AD&D adventurers belonging to this race. The five brothers are quite orc-like in appearance and could pass for the real thing to the untrained eye.
