I need to parent one quaternions rotations to another.
I cannot find any page concerning the math behind this, could anyone point me in the right direction?

how would you prepend?
and what would doing that do exactly?
excuse my noobism, but I only just started to grasp quaternions in the past 12 hours...

Quaternions can be treated as orientation transformations just like matrices.
If ' denotes inverse then:
T * T' = Identity
C * P' = C-parented-to-P
Algebra:
C * P' * P = {thing you're looking for} * P;
Confirm:
C = {thing you're looking for} * P;
