Ancient Fortres [RoN,4ply]

A map made for Reign of Nether, featuring four starting islands and a central fortress connecting it all. Space is limited so it should be used wisely. Similarly, metal is limited in the starting area to encourage expansion.

Every island has two bridges which could serve as an alternate path of attack or reinforcement, but they must be opened from inside the fortress using the golden pressure plates located at the corners.
