Rule 309.5a
Official source text from the 30 July 2024 Rules release
If a player ventures into the dungeon while they own a dungeon card in the command zone and their venture marker isn’t on that dungeon’s bottommost room, they move their venture marker from the room it is on to the next room, following the direction of an arrow pointing away from the room their venture marker is on. If there are multiple arrows pointing away from the room the player’s venture marker is on, they choose one of them to follow.
