Card Lores:Patroldroid

It is one of the scouting-droids that patrol over the cities during night time. One day, it encounters an abandoned laboratory which is still running underground. As it checks around the place in order to report its finding, it accidentally hits itself into a wall. The place is old, a decent quake cases one of shafts to fall and crashes into the mysterious running machine, which causes an explosion. After activating self-recovery, it finds itself ended up in the same laboratory, but with a weird hole that tears apart the dimensions in the thin air before it. Exotic creatures from the other dimension start to come out. And the new legend to be written in the history is bound to begin.
