Don't worry about sneaking through the sewers, as you won't encounter any enemies that will hinder your progress. You are likely to encounter nothing but small, nuisance along the way, which are easy enough to deal with. Once in the sewers, start following the arrow on your compass, the path through the sewers is very straightforward. Use the key that Vicente provided you with to unlock the gate.

Once inside the prison, you then must locate Dreth and put an end to him. You'll need to sneak into the prison via the connected sewers.

Dreth is currently behind bars in the Imperial Prison, which is the same place you broke out of at the start of the game.
