This vast webbed network of tunnels is a hodge podge collection of everything from basements of old demolished buildings to war bunkers and tunnels. Burried under a city as large as London and Time have taken their toll and made them extremely dangerous, especially for fragile beings, but if you're willing to risk getting lost or hurt to find your way they can prove useful. Very few people have ever mapped it, even those who have only have small portions of it down.
