Headcanon (sometimes called personal canon) refers to personal beliefs held by members of the Otherfaith about our gods, spirits, otherworld, or religious matters. It is related to canonical belief in the Otherfaith. Headcanons can involves what offerings a god prefers, the specific of an individual spirit, or the landscape of the otherworld. Personal practices - such as the details of how one prays - do not truly fall under 'headcanon' as the term refers to beliefs or opinions rather than actions.
The People borrow this term from fan communities in which people differentiate between the official canon in fictional universes from the personal ideas and fan theories that pop up in fan communities and fanfiction. We use it instead of unverified/unverifiable personal gnosis (UPG) or shared personal gnosis (SPG).
