sounds fantastic! maybe he became a slave to the witches after the war ended and damian, i think he would have been like 20-21 at the time, freed him and let him escape to a rebel camp? i have damian as being very fluid in his neutrality, and i think deep down he felt somewhat responsible for them since his own brothers turned out to be human. if marcus remembers him, i think it would be awkward if they met since they are on opposing sides!
