Halikaarn: A Saunt from the last decades of the Praxic Age who clashed with his contemporary, Proc. Sometimes called Saunt Halikaarn the Great. Broadly speaking, Halikaarn is seen as the standard-bearer of the school of theorics promulgated thousands of years earlier by Protas and Thelenes and carried forward after his death by his disciple Evenedric and the Semantic Faculties. (From the Glossary)
Halikaarn, as Saunt, was patron of the Semantic Faculty of the Concent of Saunt Muncoster.
Perhaps Earth correlate of Kurt Gödel or Georg Cantor.
