Necrohall

Necrohall is a building located in the Devoron System on the planet Nihilon. The building serves as the headquarters of the Order of the Deathslingers. 
Before the Deathslingers took residence, this building was once the seat of power for the native inhabitants of Nihilon, the Khrall. The building was said in Khrall mythology to have been build by the Goddess of Suffering, and the echoes of screaming are said to be heard throughout the halls. When the Khralls went extinct sometime before 2100, the building stood abandoned. When the newly formed Order of the Deathslingers came across Nihilon in their journey to find a home, they saw the building in perfect condition, despite the decay of the rest of the planet. They immediately made the building their headquarters.
