Secret Portals in the Sewers

As the Undercity map shows, there are many secret doors in the sewer walls, and labyrinthine passages beyond. Who built these is unknown, but some lead to the lairs of dark and evil folk-Clannair Black shadow (see above), the lair of the Cult of the Shriven Sickle (see below), and others. Few sewermen know of these entrances and exits; the DM should determine whether any such man does know about such a portal, depend ing on adventure needs.

However, these numerous portals do mean that unexpected denizens may be encountered traveling the sewers. Encounters with unusual NPCs should be used carefully by lhe DM with a view to the larger-scale adventure to which such an encounter may lead.
