The party just finished kicking down the door and winning a battle with an orc (I am the DM)
Rogue: I loot the body
DM: Inside his pocket, you find a photograph of the Orc with his wife, proudly holding up a little orc baby. On the back is a note, reading ‘Good luck in your new dungeon! Can’t wait for you to come home (just in time for another one!)
Cleric: …I want to run a history check on the orc (rolls 17)
DM: The Orc’s name was Edward. He was the tribe of Oo’rash, but traveled to Thane to work as a guard to afford money for his desperately ill son’s medication. Against all odds, struggling racism and mistrust, he managed to secure a job as a guard in the dungeons of the castle, where he used his diplomacy and giant heart to reform invaders into becoming better people.
