Luca
Luca is as alien to this world as the elementals and demons summoned by brave and foolish spell casters. The world he came from was called Earth, where he was a priest in training in the city that was the center of one of the world's largest religions. There he was specializing in tracking down and eradicating demons that crawled their way up from Hell. In this world demons and angels were beings of myth, and exorcists were seen as saviors by some and charlatans as most. Secluded deep in the forbidden libraries of the Vatican, Luca had stumbled across a very old book apparently forgotten by all. The spidery and cryptic lettering across the spine made his skin crawl, but the scholar in him could not resist, and he opened it. The words directly on the inside cover called to him, and he worked to pronounce them out loud.
As soon as he read the last syllable, the world spun around him, and the words burned with an inner fire. There was a sense of falling followed by slamming into something, and Luca blacked out. When he woke up, he was staring at a sky with two moons, and the tribe of small, green skinned humanoids was going crazy as he bleed onto their most holy of holies. Before they could sacrifice him, the wisest of them, the keeper of their lore and legends, recognized the Sect tattoo on Luca's head as part of a prophecy the shaman's in his tribe had never thought would come. He stopped his tribe, and took Luca under his guidance, teaching the big human the goblin language and culture, as well as what he knew about the outside world.
Eventually the shaman read the signs, and felt it was time for his student to depart. Another goblin went along for the journey, a foul mouthed young goblin dubbed simply Speaks. The two became friends, and Luca became the only human Speak's trusted. For his part, Luca's eyes were opened wide at the numerous cultures on this vastly different world. Here magic was real, and the divine was there for everyone to see. Or so he thought. They finally arrived in Corisca and went to see a display of divine powers at the local university, where aspiring students would show their prowess to the locals. A man broke up the event, branding the priests liars who no longer had any connection to their gods and fooled the common man simply for gold. Before the man could be taken into custody, an explosion rocked the event, killing and injuring hundreds. Luca went down to the arena floor without thought, intending to help as many as he could.
Real healing energy poured from his hands, surprising him as much as the man who had branded the priests liar, who was near him healing other in the same manner. Luca healed as many as he could before exhaustion took over, and he collapsed against a wall. The unknown holy warrior stopped some time later, sitting next to Luca. The two talked for some time, the man sharing his views with what he considered to be a true cleric in the time of no gods. He told Luca of how the gods had abandoned most, but there were a rare few who had not lost their holy magic, and how this fact was being covered up by all of the churches who continued to charge money for magic they could no longer cast.
The next day, Luca was getting ready in his room to depart the inn when he heard a scream from Speaks's room. Luca charged to his friends defense, but not before the deed was done and the murderer escaped out the window. His friend dead, Luca now truly wonders just what god watches over this world.
