Back to the Dungeon
The heroes enter the cave and descend the stairs art the back, entering the first room of the dungeon which is as far as they have yet penetrated. Now, when they enter, they see three orcs seated around a table [the purple thing] and another orc nearby to the south. All four orcs immediately draw scimitars and glower fiercely at the adventurers as they move to attck!
[Roll initiative, someone, please!]
[And remember, PCs and NPCs can move through an ally's space, but not an opponent's space.]
