Aragon contemplated the man sleeping in the Halls of Healing. The man had not lied when he said he could help. He had worked on solider after soldier in the Halls until he himself dropped from exhaustion. Many men of the West lived because of this man. Even soldiers with the (up to then) invariably fatal stomach wounds had lived, instead of dying with high fevers and screaming pain that no herb could alleviate. Amazing indeed, but in accord with the way he had come to them.
The stranger had appeared in the aftermath of the battle of Pelannor Fields. As the exhausted men of Gondor and Rohan searched for survivors, there was a whine like insects in a field and a sparkle like summer sun on a lake - and a man dressed in dark trousers and a bright blue tunic, surrounded by silvery boxes, just appeared. Instantly the soldiers raised swords, spears, and bow and arrow and pointed them at the figure. For his part, the man looked stunned. Seeing all the weapons pointed at him, he slowly held his empty hands away from his body. "I take it that this isn't Starfleet Hospital 3?" He looked around, and muttered, "God damn transporter."
