Silicon based lifeforms of a hardened crystalline figure, who emerge from the depths, arising from down-below to explore the overworld.
All Shardminds are a physical fracture that separated from the grand astral gate beneath the surface of the Eard-Hnecca mountain range, which was destroyed in 987CE during the great war against Yuan (c.985CE-1000CE).
Though new Shardmind are born from spawning agodes beneath the Mountain range, those born of the gate are generally - culturally - held to be wiser & more venerated than their younger kin.
Individuals of the Shardmind oft stand between 5'9" & 6'3", with little variance there upon. The tallest Shardmind to have ever lived in NĂ¡darrac's overland was considered freakishly tall - standing at 6'4". As for Shardmind who have only very recently emerged from the undergrounds, they tend to stand a might taller, between 6'-6'5" roughly. Eventually shrinking as they live more and more above the surface.
