Tales of Auriga
The Silics are slow moving elemental creatures, heavily affected by the presence of Dust. They are often found guarding great underground ‘crystal’ farms. Rumor amongst the archeologists and explorers of Auriga say that these crystal farms are how the Silics reproduce.
While the Silics are usually harmless, barely animate creatures, they are excited by Dust, and consuming it allows them to become stronger, faster, and more intelligent. Silics can often be enticed by Dust as a payment to perform tasks or missions.
