May you please clarify the difference between a heir and witch’s familiar alongside with how the interact with them? The original explaination was a bit vague, sorry.

It´s vague honestly, and there is some nuance to each case, but it does seem like Heir Familiars are more subservient to begin with, while Witches have a sort of tug of war with the powers of said Familiar- Think John just sending WV off on a Windy Quest shortly after meeting him, versus Jade’s almost Lusus-like relationship with Bec.
