Bestiary entry from the Clan Primer:
Bestiary Observations
“Being a variety of giant tortoise spending its infant stage quietly beneath the soil, only to emerge upon maturity.
It is a quality of the giant tortoises that, depending on how deep down in the earth their youth was spent, the composition of their shell, and thus the particular species to which they belong, comes to differ.
Of their ilk, the silicon tortoise has spent its youth in the deepest of tenable places, being born with a thick layer of fat inside its shell so as to sustain its growth without the need to eat.”
