Ashana

Nul's high point, if any portion of the system can be so called, is the fifth planet, Ashana. Ashana is home to the single thing that might someday transition the system from slaver hell to tourist attraction: a city built out of a wrecked Human battle carrier.

Olympus
Olympus is a settlement on Ashana (Nul V). Built in the remains of the carrier UEES Olympus.
