Hades' fort

Hades fort is the most notable entrance into the layers. Several incursions have launched attacks directly into spawn from here, and the entrance allows for thousands of troops to move in at a time, making it an ideal stealth method. However, the reverse also works, and as such it is an important place to hold, due to it being deep in the heartland. Because of this, troops from every faction are placed here and kept in the dark on politics so as to keep them unified. This has worked so far, as Hades fort has never been taken. It is said that items casted down into one of the smaller entrances away from the main cavern causes items to be lost forever if casted in, and is where the large majority of ultra weapons were sent. None of these lost ultra weapons have been seen by anyone, and are even lost to the gods.
