Some people seem to get them confused with the Grendl Stars (Home of the hyper-violent Barghesi alien species) and the Halo Zone (Any area beyond the light of the Astronomican - mentioned as being a border where Lord Solar Macharius' forces would go no further)
The Halo Stars:
- Are guarded by the Death Spectres chapter. They keep the 'supernatural inhabitants' in check.
- Also houses the Cythor Fiends. Vicious bat-like creatures, who may also be the Space Vampires.
- Is an area of space where no one, except daring Rogue Traders will go
