Map of the Underground Tunnels below the Garden Deck

My quick reference map if the party enters the underground tunnels on the Garden Deck. If they party just explores, use the chart above. If they chooses a direction, they will encounter the Umber Hulk, but they will see it before it sees them and they have an opportunity to evade or surprise the beast. If the defeat the Umber Hulk and continue down the corridor it just came out of, they will find the inactive Driller Droid.

Turn Valve Door requires a successful Force Doors roll. If they succeed each will be washed to a random location. Circled Back to Start means that they are now at the bottom of the river. Burrows are now flooded and impassable.
