Late is the hour, dark the night. Clouds blanket out the moon and stars. A lone figure is seen slipping out of the forest and onto the main road leading into the village, in search of it's doctor.
An agent of the Vatican, Father Titus is one of it's highest ranking and most effective special agents.
A race of beings actually IS invunerable while in adolecence. They age, but cannot be killed. A miniority of the race (1 in 20) does not become invunerable, but rather becomes immortal at some point in thier adolecence, and ceases aging while being vunerable to death in all the normal ways. Another minority (also 1 in 20) Permanatly becomes invunerable after adolecence, but ages twice as fast as the race normally does. There is no known way to test for which of the three traits an individual manifests and the three traits cannot mix, as they are tied to the same gene, as it were.
