Character
The Character of Chiaroscuro was created in 1994, and joined FurryMUCK in November of that year. There, he was co-creator of Itza Castle, which was (In Character) based on the ruins of his home in the 10th century and magically incorporated to blend with a Kzin spaceship owned by Jamen-Riit. His middle name of 'Lyle' came from his modern adoptive family of Alice and Larry Lyle.

He is a temporal magician on a subatomic level, able to manipulate particles en masse in order to alter, reverse, and change the flow of time- within certain limits so as not to damage the temporal fabric. He focuses this magic through the use of pebbles, in the way other magicians would use wands or wards.

He also appears on FluffMUCK, and on Second Life as Chiaroscuro Mounier.
