Rock Hermits are members of a space faring race which have decided to live a life of isolation inside a hollowed out asteroid. They may be retired traders or military personal or simply average citizens who wish to live a reclusive life.
The Rock Hermits life is not entirely without danger. They are at risk of being mistakenly targeted by asteroid miners, although a hollowed out asteroid provides few minerals and any sensible Rock Hermit will attach a beacon to notify of their presence.
Rock Hermits will have a ship, often a Krait as a means of escape and resupply.
