Obviously, this step is ignored if we're not building a space station.Trill is always located in a random dead end picked by the map generator. An iris door is used to lock Trill, so it must make sure the facing cell is between 2 walls to hold the door. To reach the facing cell, we use the root direction.
When we have found a suitable place for Trill, the generator stores the location in memory and counts the number of steps required to reach the root cell. It then repeats the process of finding a different place for Trill and counts the number of steps again. If the number of steps is greater than what was last stored, the last stored position of Trill is replaced with this position. The generator does this 256 times to ensure Trill is as far as possible from the root cell.
