Born into Keon under the prior Sectuib, Sergi is fulfilled as Risa's First Companion, though neither health care nor administration is his calling. He is artist and metallurgist, feeling a strong kinship with Hugh. However, he often wonders what his life might have been like had he pledged to Zeor to become Klyd's Companion. He doesn't realize what the Farris touch on him may do to Risa, or her relationship with Klyd Farris. Sergi and Risa have a son who's name is Mor Kreg ambrov Keon.
