Bluelight

Bluelight was a personal cantrip that apprentice wizards could learn. It created a sphere of light that softly illuminated the immediate surroundings.

Effects
When cast, this cantrip created a diameter sphere in the palm of the caster's hand that gave off a soft, blue radiance. The light reached only away in all directions and did not reveal anything beyond that radius. Because of this, a viewer from far away was struck by an eerie sense that something was not right. Bluelight did not inhibit or hinder natural or magical infravision or ultravision. The glowing globe lasted as long as the caster maintained concentration on it.

If the caster held an alicorn when casting bluelight, the sphere of light formed on the unicorn's horn rather than his or her palm, and moved with the alicorn. The radiance continued to emit from the alicorn regardless of the distance between it and the caster, for as long as the caster maintained concentration.

Components
This cantrip required verbal and somatic components. The caster extended an open palm and spoke a simple rhyme that included the words "blue" and "light". ("Show me true, light of blue," for example.)

History
This cantrip was described on page three of Bowgentle's Book, penned by the famous mage from Silverymoon.
