The watcher, clad in armor of shimmering dawn, guards the bridge that connects the realms of mortals and gods. Repelling dragon hordes is easy when one possesses stamina as eternal as an immortal sun. And like the sun's rays sweeping across the land, so too does the watcher's gaze extend far and wide, scanning for signs of the end-time. Then with a blast of a horn, the watcher's sword will welcome the formidable foes that have come to silence this golden sentry.
