Not in the posted file, as I'm waiting for the current round of character creation to finish...probably has now so I'll go post it soon, but in the meantime...
Nymph Relationships
Sister: Term of affection given to all other Seelie Nymphs as well as any other woman a Nymph considers a friendly peer.
First Sister: Rare term used between Nymphs that share the same mother.
Soul Sister: A close friend and/or lover, the male version is Soul Brother. It is a step between Sister and True Sister.
Soul Mother: One part mother, one part Soul Sister--Nymphs born from parthenogenesis always have a Soul Mother, whereas those who are born from a Nymph mother sometimes do not, though the birth mother often honours a Soul Sister or True Sister by naming her the Soul Mother.
True Sister: Someone who's heart is bound to her true sister, and their souls sing together in perfect harmony. A True Sister is a rare find, and it is a relationship to be treasured. It is by no means exclusive of other Sisters, however, or even other True Sisters.
Note: This is only accurate for Seelyne.
