Start of fight: Two mostly empty rooms; just a table and a few chairs and 10 watch. then, a long hallway, with locked doors every once and a while, (DC requires a key) and then the main room. Once in main room, way to library open, and unlocked, however there are 3 Ebon Guards with 4 Duskrunners hidden, waiting to see what they find. Once something is found, their trap is sprung, and they hop out of hiding. If they get away, the 4 DR chase them, to meet John and 3 Shrooms to save them time, around 4 rounds. Then DR will chase, if they remain in one place for more then 2 rounds 1d4 more DR appear, and more every 2 rounds.
