Francisco Diego del Belmonte
Junior to Montano but senior to Gratiano, Boukephos was a force to be reckoned within the Lasombra hierarchy. To young Cainites during the War of Princes, Boukephos was the one of their elders who stayed current with the times.
Like his sire, Boukephos was a notorious wanderer, often absent from politics while educating his childer and grandchilder (including his great-grandchilder, as Talley the Hound can verify). He was one of three elder Lasombra that knew the Obtenebration power of Tchernabog, and was considered one of the true masters of Obtenebration (the Antediluvian and Montano being the two).
