“Pulses” of the Current are also known as the “Great Houses” of Sabretooth Clan and branches of the Families bloodline.  They are sorted by the archetype of the specific patron Zoa (guardian spirits of the Family).   During Inner Courts events and the Conclave members of the Family can be “sorted” into a Pulse befitting their personality and chosen virtues.  

However, do not let these focuses limit you as everyone has a dominant Pulse and a secondary one. For example one might have dominant in Mradu, yet be very much a Kitra in other aspects.
