Well ten anyway. Ten more aliens for your OSR space setting, ranging from the aloof Beanpoles to the friendly (if gluttonous) Phrogues. Plague your crew with nanites, intrigue them with the undead Qaptos or let the four limbed Tenebrians give them an itch. The Galavy has a hundred million stars. Start populating them.
Aliens Capsules Book 2 is fully compatible with White Star.
