SubGround

The SubGround is an underground network of systems to travel within, consisting mostly of defunct subway lines and maintenance tunnels, although some walkways were added after the wars. For the most part there are hatches, stairways, and maintenance doors for legal use. Almost all of them are within the city.

There are four known external entrances set into the wall itself, guarded and maintained for what little legal Spawn use passes through.

There are a few smaller entrances in manhole covers and hidden back rooms. Black market dealers and undesirables are usually quick to hide them and keep them for personal use, charging for the privilege for others. If one is clever and knows the systems well, even Spawn can take paths to avoid ever seeing a guard or security system. They won’t fit out through the manhole covers, but they can fairly easily rendezvous with those inside the city in the tunnels underneath or at any number of landings where a few paths meet.

For this purpose there are two “hidden” external hatches a little ways into the Outlands that allow entry to Terminus. All other tunnels (that are known of at present) have collapsed, otherwise leaving the Outlands and Terminus as two separate SubGround systems.
