 Kalashtar psions and the Inspired lords of Riedra have found a way to harness the power of Siberys shards by undergoing a painful process that embeds a shard in their body, providing enhanced mental or physical abilities.Khyber shards are found beneath the earth near layers of magma or sulfur vents, typically growing on volcanic cavern walls.They are found throughout Eberron but are particularly common in areas known for fiendish activity, such as the Demon Wastes.
