This spell requires something which can draw on the power of the sun, something that has once lived, hence the bone of a Keldian must be used. The Red Cloak enchants the bone over three days, casting the spell once on each day, and it becomes wreathed in undying fire which casts a glow like the Red Sun over an area 6 strides across. Should a Red Cloak grasp the bone and destroy its magic he can cast spells as if during the Brilliance on the Light Side, regardless of where he is.
power+10 strides are lit per Power Level
