Located north of the galactic core, Boreas (Northern Wind) is a distinct white region within the Norma-Outer Arm. It is bordered by the golden Eurus region to the east and the blue Zephyrus region to the west.

Located centrally in Boreas is the Tristar Beacon, marking this region as the last safe shores for exploration vessels with jump ranges below 30 LY. Ships with limited range wanting to proceed north are advised to travel east to the borders between Boreas and Eurus before attempting to cross the treacherous Styx region.
