Cavia
The animals who gained intelligence and speech in Albrecht's Void experiment, and who carry its grief together.
SANCTUM · VOIDFULL SPOILERS
The members
Fibonacci copes through calculation and control, Bird 3 through emotional openness, Tagfer through anger and grief. Their recovery as a community is a matter of understanding one another's different defences.
How they see Albrecht
The man who saved them with knowledge is the man who endangered them. For that reason the Cavia never declare Albrecht a hero or a tyrant with one voice.
The Sanctum duty
They provide research and defence against Murmur attacks. Progress through their standing also stands for the reopening of personal wounds.
