The K'srn are a poorly understood Reshat race who are believed to have reached their apex some time after the time of the L'panim. The K'srn had writing and sophisticated artistic traditions, but their glyphs have yet to be deciphered. Very few K'srn ruins remain, and they are located beneath the Underdark.
The K'srn had brown skin, wide heads, solid green eyes, and were completely hairless. They were tall and gaunt, with hardly any muscle. Based on carvings, it seems that they adorned themselves with robes.
