Official Volition Node Map
Volition released this map in 1998 as the standard reference for all jump nodes in the FreeSpace Universe. While FS2 adheres to this map for the most part, there are unfortunately some conflicts between what we see here and what is documented in FS1. See Node Inconsistencies for a list of these conflicts.
The systems on this map do not adhere with the stars' positions as seen in the night sky from Earth (for those that exist in real life).
