The Masked Man, which is the only name that the majority of the Kindred community know him by, has very little public knowledge in the know about him. Most know he's of Spanish descent, which explains the link to the Lasombra and the Sabbat, both of which had heavy ties to Spain in their time. 

Mexico City was his next known location after many long years of hiding in the shadows and operating as Paladin, protecting the Sabbat from both discovery and downfall, before his promotion to Priest. Religion had been a long standing element of his life, and it became evident that still stood when he took on the new role. Continuing his ascent, bishop to archbishop, The Masked Man hasn't been seen for hundreds of years, but the rumours swirling around Pennsylvania are that he's making a resurgence, if you know the right places to look. Perhaps they're true, or perhaps just a horror story to tell the younger kindred, like the boogeyman, hiding ever in the shadows.
