Tyr's Might

You open a gateway to the light of the stars. A 20-foot-radius sphere of bright light and warmth appears, centered on a point with range and lasting for the duration. This aura is filled with a cacophony of chimes and bells that can be heard up to 30 feet away. No darkness, magical or otherwise, can dim the area, and creatures fully within the area are blinded.

The aura creates a warp in the fabric of space, and the area is difficult terrain. Any creature that starts its turn in the area takes 2d6 fire damage. Any creature that ends its turn in the area must succeed on a Dexterity saving throw or take 2d6 radiant damage as branding chains lash against them.
