In the entrance to the crypt, carved in stone, one can see lettering, deeply etched into the rock.

Ishak Rules
1) Proper reverance is to be given to your coven leader.
2) Show enough wisdom not to fuck with other coven leaders, you will not bring such chaos on to my doorstep without permission. As for the other coven members themselves...that is your choice.
3) If you come into trouble with other vampires or covens, you may come to us. We protect our own.
4) The vampires of other covens are of no consequence to us, but thou shalt never defile our borders with their presence or that of mortals wishing to see sunrise.
5) Killing, fucking, maiming of mortals is naturally permitted, even promoted.
6) Any dispute between coven members may be brought before your coven leader, but you will respect their judgement or suffer consequences. The matter may also be settled privately. Once the leader knows of a matter, it is within their jurisdiction.
