Дідусь Пом

An old miner who meets Sheeta and Pazu and tells them of "volucite" ("aetherium" in Disney's English language dub), the crystal that provided Laputa with its power. He reveals that Sheeta’s pendant is one of the largest and purest such crystals in existence, and counsels Sheeta to remember that the crystal's power rightly belongs to the earth, and that she should never use it to commit acts of violence.
