Adventure Background A barghest named Yeep has begun its onslaught of attacks against the Black Blade goblins. Starting with Chief Gnar, then his second in command Thrawn, the barghest is moving methodically down the line of command. Krill is now chief. But he has some problems: Two leaders of the Black Blades are dead. Who killed them and why? Is he next? Dringly, the next in command, has decided to take his lair for himself, declaring himself Chief of the Black Blades. Who are the Black Blades? The Black Blades are a tribe of goblins in the local area. They are known for dipping their blades in a dark black substance. It is rumored these blades are poisonous. The Black Blades regularly attack passersby on the road to rob them. The Black Blades have two lairs, one run by a chief who leads the whole tribe, and another overseen by a boss lieutenant. The Black Blades have a well-established pecking order which is how Krill stands to become chief. The next in line is Dringly, who has also declared himself chief and wants Krill dead. Krill suspects that there is something suspicious about two leaders being killed within a day of each other, but he has already burned Gnar’s body without any investigation. He needs to investigate the body of Thrawn, but it is in Dringly’s lair. Krill wishes to avoid direct confrontation with Dringly at the present for three reasons: 1) Any violence would only kill his own tribe members and further divide the lairs. 2) He believes there is still hope for negotiation to reunite the Black Blades. 3) He believes that if he were to attempt negotiations himself, Dringly would kill him.

Trouble Cubed is a is a pseudo-adventure with three interesting gelatinous cube encounters. These three encounters are structured in a way that they can be used together as one adventure, or each individually dropped into any adventure from EL5 to 7. The encounters vary the cube's encounter situation significantly, and the tactics needed to deal with them, such as by trapping a character with a portcullis between a cube and a pit trap, placing a cube half down a pit trap, and having the cube accidentally ingest a beneficial potion (such as spider climb).
