Lexan

Alexander, or simply Lexan, is the main hero of the Skalp books.

Premonitions
Lexan is known for his "dreams". These dreams are usually premonitions of what may happen. Sometimes, they show what others may turn into, depending on their choices. Sometimes, they're simple visions of what may come in the future. And sometimes, they're a meddle of both, mixed with a regular dream.
