An accomplished scholar of the ancient texts and prophetic scrolls found in the abbey's vast library, he eventually shut himself off from the rest of the world, going half-blind and insane from his studies. When the vampires came upon Wygol, he found a holy relic with which he could keep the creatures at bay. In his insanity, he banished the monks away and sealed himself and as many holy texts he could gather in a room in the highest tower of the abbey.
In order to defeat the Dark Lord of the Vampires, Gabriel and Zobek brave the traps the mad abbot installed to keep invaders out. Upon finally reaching the highest tower, they find him chanting feverishly in front of a statue holding the relic he so coveted. As Gabriel takes the relic, Dorin curses both of them as servants of Satan. After Gabriel and Zobek leave for the village, Dorin starts to chant again, even more feverishly than before. But it is in vain, as he is subsequently attacked and killed by Vampire Warriors.
- He shares the same name as Vincent Dorin, the monk/priest from Portrait of Ruin who sells items, weapons and armors to Jonathan and Charlotte. This is a possible mythology callback, as certain other one-time characters of the original timeline have also been either mentioned or re-imagined in Lords of Shadow.
- Like his original timeline counterpart, he is at some point attacked by a vampire (in the Abbot's case multiple vampires). In Portrait of Ruin, Vincent is bitten by a vampire and vampirized (although not completely). The abbot's counterpart, however, is more fortunate as his condition can be reversed via the Sanctuary spell (in Lords of Shadow, the abbot becomes the unfortunate meal of a horde of Vampire Warriors).
- The Abbot carries a necklace bearing the Cross of Saint James, one of the most important knight orders from Spain.
