this was the name given to the ceremony formed by the A'Mar of the moon of Lamus, in which they remembered their first encounter with the Wellspring and the thirty-year occurance of the sunless day. The original A'Mar discovered the Wellspring on the eve of the sunless day, but were afraid to drink from it. When the sun failed to rise the next morning, their apprehension only grew. At the same time, so did their thirst. After watching the coronal ring of fire move across the sky was the moon and planet matched orbits, the A'Mar finally gave into their thirst and drank from the spring. They were immediately revitalized, and the next morning saw the sun rise again. The A'Mar were not supersititious, and understood something of the celestial mechanics behind the sunless day. However, they never forgot their initial fear, and established The Vigil to ensure that the waters of the Wellspring would continue to flow. Once every thirty years during The Vigil, one A'Mar who had never drunk from the Wellspring was required to spend a day and a night at the Wellspring without taking a single drink. When the coronal ring of fire passed across the sky and set, the A'Mar could then drink from the Wellspring, thereby ensuring that the sun would rise again. During the Galactic Civil War, the sunless day occurred at a time when only one A'Mar child had never taken a drink from the Wellspring.
