Mirror Lake is a body of water in southeastern Yurukan, the second largest on the Aban Steppe behind Tomb Lake. There are no rivers that feed the lake, at least no permanent ones, as it is instead fed by many springs deep below. Known for being impossibly still, nothing seems to stir the waters of Mirror Lake for long - passing winds do not affect it, and even splashes made by jumping in or throwing something into the waters rapidly recede as the surface becomes placid once more.
