During Moonquake Pluta, he gallantly carried his fiancé Astrid through the hallways of Hotel Copernicus to save her from the wreckage. Unfortunately, his luck finally ran out mere seconds before the quake was over, and he was pinned by a boulder, barely having time to throw Astrid out of the way. Ulysses watched in horror as another boulder fell on her anyway. In a fit of adrenaline he wrenched himself free, but was too late to save her. His last action was to fashion a coffin for her from the wreckage and bury it in the rubble with a plaque taken from a dead Guard. Afterwards, though he refused to commit suicide, he also refused to eat or drink. He was nearly dead already by the time the Hotel collapsed and sealed him in forever.
