Loftus

From Glen Cook Wiki

Loftus is a soldier who joins the Black Company in Beryl as the Company heads south in search of Khatovar. He joins with his brothers Longinus and Cletus. All three desert the Beryl Urban Cohorts to join the Company. They are excellent engineers and are the primary people responsible for building and maintaining the Company's artillery (ballistae), seige works, and so forth.
