Bestiary entry from the Clan Primer:
Bestiary Observations
“Being a dragon that has lived in darkness for such a great span of time, its eyes have withered, yet its sense of touch has grown so acute that it may sense the slightest source of heat upon the air, thereby distinguishing obstacle from foe.
‘Aevis’ summons to mind the word for ‘demon’s armor’ in an ancient tongue, and indeed, the wyrm’s carapace is as impenetrable as the hardest steel.”
