"Y"arkovan Gateway Network

Lining the maze of tunnels beneath "Y"arkova's surface is a vast array of doors. These doors are referred to as Gates. These gates when opened, create a sort of wormholesque pathway to a similar gate at another location. These locations could be on different planets near or far (even out of the known sector), or even other dimensions and planes of existence.

The pathways are referred to as Bridges and appear as an empty white space with only a bronze or brass-like metal pathway leading a short distance to the exit gate. One cannot leave the path as it is bordered by a seemingly invisible wall and ceiling.

Caution: If upon opening a gate an empty black space appears instead of the described white space, this indicates that the connected gate has been destroyed. DO NOT step into the empty black space as this will result in your immediate demise via disintegration.

Note: Only the first three levels are allowed to be extensively detailed on public records as the Hive of the Iron Queen has deemed the fourth and fifth level forbidden due to the extreme risk and danger involved with the tunnels and gates themselves and the contents of said gates.

The gates come in five varieties based off what level of the tunnel system they are on. The first three level's gates are categorized by the materials that make up the gate and are as follows: Level One - Wood, Level Two - Stone and Level Three - Metal. All gates of these levels look like typical interior and exterior doors or reinforced vault and ship doors.
The Hive of the Iron Queen has given these cryptic details on the structure and classification of the fourth and fifth level gates: Level Four - Sphere, Level Five - Fractal.
