Lore:Aura of the Righteous
Insomuch as all fell things abhor the light, so has Stendarr gifted all those who invoke His Name with the ability to clothe themselves in a righteous aura of blessed light. Over time, even as evil's many Abominations found new ways to afflict Tamriel's mortals with destruction and death, the Priests and Resolutes of Stendarr have adapted Stendarr's glowing gift to many purposes, whether to smite, to defend, or to heal.
For offensive means, Stendarr's gift most often manifests as a piercing beam of light, resembling a spear of purifying sunlight and oft referred to in those terms.
As a form of armor, Stendarr's gift may take the form of a diffuse aura that surrounds the righteous, mitigating the attacks of the abominable, or it may focus into an almost-palpable shield to ward off a specific threat.
Worshipers who eschew all forms of violence, such as the Harmonious Masters of Lillandril, have turned Stendarr's glowing gift into a tool for healing, and then freely spread their knowledge of cleansing and healing rituals, even to Stendarr's more militant adherents. For even in the hands of a warrior, how can the curing of ills be an ill thing?
