Acknowledged, by word of Erasmus, Prince of Fredericksburg, 2003
Dimitri Marcellus was embraced by Jenna, childe of Archimedes in the Warrens of Fredericksburg before it fell to the Sabbat. He came topside long enough to gain Acknowledgement from Prince Erasmus, and observed the doings of the court, helping out as he could until the Sabbat stormed the city, devoured the Primogen, unleashed monstrous Vicissitude-twisted nightmares, and killed or drove off the Camarilla Kindred in the area. Overmatched physically, Dimitri went down below and stayed there for ten years, feeding on rats, sewer workers, homeless, and the occasional random animal or forbidden places enthusiast that wandered in. He tended to business in the sewers, serving the needs of Archimedes and the rest of the clan until recently, when Camarilla interests began to take root once again.
Maybe. Ask Jenna.
