Aaaahhh, I didn't realize there was a time limit on give stone! I take that's so breeding will be limited to a single thread? That makes sense!
In that case, having the sensorial link be the only part of the contract makes far more sense. In honesty I was planning on having the link be part of it all along, so that then information can be quickly shared between Gabriel and the covenant; my thoughts were that this seems quite intrusive but would be valuable to their cause.
Added that to the top post!
In addition, I feel that chipping almost all of the covenant's stones would be slightly counrer-intuitive as it risks damaging the gem that could be used for other purposes.
And yeah, we were discussing that in the chat!
It'd definitely open the door to some interesting plots, like characters becoming fugitives or even rebellions against the cult, or even more peaceful exits, in which the character is allowed by Gabriel to 'leave' peacefully, however with a debt on their shoulders. In this case they may be sought out to do dirty work again despite not being a member of the covenant anymore and being looked down upon.
