Pralix

Pralix was a Tytalus maga who, in the ninth century, founded House Ex Miscellanea. She was pupil to Guorna the Fetid, along with Tytalus and Tremere, and later joined House Tytalus as the Order formed. She orchestrated the battle against Damhan-Allaidh in the British isles, which ultimately resulted in the formation of the new house under her leadership. She also founded the magical tradition of the Line of Pralix within the House to facilitate the acceptance of exoctic magical traditions into the Order

Contradicting Fifth Edition Material

Page ten of the Fifth Edition Core Rule Book indicates that the threat of Damhan-Allaidh came in the early ninth century and that Tytalus the Founder himself gave the task of defeating Damhan-Allaidh to Pralix. However, in discussing the state of House Tytalus following the founder's dissappearance in 807, after describing how Hariste became the first prima of the house, Houses of Hermes: Societates goes on to describe how Hariste manipulated the Order into sending Pralix after Damhan-Allaidh. The latter treatment is probably the more reliable as far as canon in so far as the core books treatment of the events was by necessity short and in so far as the latter agrees with the timelines presented in prior material.

Publishing History

Pralix was introduced along with all of the Houses for the first time in the 1989 Lion Rampant Second Edition product named Houses of Hermes. In that version, she is a "senior filia of Tytalus". In that version, the Robes of Dusty Dawn were given to Pralix by Verditius. The timeline for her battle against Damhan-Allaidh was 814-816 A.D.

The 1994 Wizards of the Coast supplement Lion of the North give a longer description of the fight against Damhan-Allaidh and the formation of the House. It gives 817 A.D. as the year the House was accepted into the Order, which agrees with the year given in the House Ex Miscallanea section of Houses of Hermes: Societates. This supplement also introduced into the history a return by Damhan-Allaidh which was not a part of the Second Edition version and does not appear to have carried over into Fifth Edition.
