Tunnel of Abbar Savi

The Tunnel of Abbar Savi is a pocket dimension connected to the elemental plane of water. It is a sort of long bridge leading between the city of Sigil in the plane of concordant opposition and the prison in which the marid Abbar Savi was held for centuries.

The tunnel resembles a long tunnel of swirling water. There are fish and other sea creatures swimming in the swiftly swirling water and the sound varies from a deafening roar to the sound of a babbling brook depending on where in the tunnel one is.

At one end of the tunnel is a large shrine to Abbar Savi, built by a group of kuo-toa from the city of Gorolosh who worship him as a god. Beyond the shrine is a portal leading to Greywater Manor in Sigil.

At the other end of the tunnel is the prison which held Abbar Savi. The prison is nothing more than a location, there is no structure or building of any kind. Abbar Savi was prevented from leaving a small area at the end of the tunnel until he was eventually freed.
