Coteries, XP spends, and you:
With the introduction of the new three “main” coteries, we are taking an idea from the core book and giving these three coteries starting dots, enough to reach Chasse 1 and have a coterie haven 1. After that, your coterie will need to work and spend xp to get cool stuff like haven amenities and more secure turf.
As for xp spends to the old dissolved coteries, you will be able to reallocate that xp immediately to other things on your sheet (not to your new coterie).
This all said, nothing in the rules is stopping anyone from having “secret” coteries that have clear, defined goals and tenets but that operate outside of the Spine, Hilt, and Blade.
