The sewer is a network of tunnels and splits into sections. Further down the caves is a goblin camp. In the tutorial level a section of the wall will crumble and rats will attack, followed by a third once you've entered — rats also drop rat meat which can be used in Alchemy. In this area there are a lot of items. In a chest next to the doorway there is a Rusty Iron War Axe and some gold. In a corner there is a Skeleton. If it's searched there are some Iron Arrows and a Rusty Iron Dagger on it. It will also carry two pieces of Armor — Rough Leather Boots and a Rough Leather Cuirass.
Also lockpicks and a torch can be found. Alongside the Skeleton there is a sack with at least one item of little use. Next there is a Rough Leather Shield and a Rusty Iron Bow. A chest alongside that contains some gold and a sapphire. In the next corner there is a barrel containing another Rusty Iron Dagger, a club and some Iron Arrows, there are also a few lockpicks. Finally, there is a small crate containing a club, more lockpicks and some torches. At the door there is a dead Goblin Shaman which has the Key for the door and two magic Scrolls — Chameleon and Flash Bolt. Also there are some lockpicks, a club and a Weak Potion of Sorcery.
In the main quest the Hero entered after one have chosen class and Baurus gives them the key. At the end of this section, they are asked to finalize the race, class and Birthsign. They will come out just northeast of the Imperial City. This area is off limits after the Tutorial quest is completed.
One is allowed to enter again during the quest "Scheduled for Execution." However, exploring is limited by just a few areas.
