Liaison describes one of many relationships, usually sexual in nature, that avout must declare publicly before their Math. These relationships can vary from extremely casual to all but married in the eyes of the Math. The Discipline prohibits secrecy about personal sexual relationship in order to prevent any sort of personal intrigue among the avout.
- Tivian is the least committed liason-type recognized at Saunt Edhar.
- Etrevanean is recognized at Saunt Edhar.
- Atlanian is a liason between an avout, typically a Decenarian and an extra which can only be consumated during apert, named after an avout who wrote love poems during the separation.
- Perelithian is the most serious type recognized at Saunt Edhar, equivalent to marriage.
- (1) In Old and later Orth, an intimate (typically sexual) relationship among some number of fraas and suurs. The number is almost always two. The most common arrangement is for one of these to be a fraa and the other a suur of approximately the same age. Liaisons are of several types. Four types were mentioned by Ma Cartas in the Discipline. She forbade all of them. Later in the Old Mathic Age, a liaison between Saunt Per and Saunt Elith became famous when their hoards of love-letters were unearthed following their deaths. Shortly before the Rebirth, several maths took the unusual step of altering the Discipline to sanction the Perelithian liaison, meaning a permanent liaison between one fraa and one suur. The Revised Book of Discipline, adopted at the time of the Reconstitution, described eight types and sanctioned two. The Second New Revised Book of Discipline describes seventeen, sanctions four, and winks at two others. Each of the sanctioned liaisons is subject to certain rules, and is solemnized by an aut in which the participants agree, in the presence of at least three witnesses, to abide by those rules. Orders or concents that deviate from the Discipline by sanctioning other types of liaisons are subject to disciplinary action by the Inquisition. It is permissible, however, for an order or concent to sanction fewer types; those that sanction zero types are, of course, nominally celibate.
- (2) A Late Praxic Age bulshytt term, as such, impossible to define clearly, but apparently having something to do with contacts or relations between entities.
