The mechanicreche is an unseen technology alluded to in Metroid Prime 3: Corruption. In the past, it was used to create Elysians. The mechanicreche is mentioned only once, in the SkyTown Data entry "Gift", located in the Arrival Station. In that script, the author recalls the birth of The First Elysian, who "stepped out of the mechanicreche 1,450.82 years ago." Whether the mechanicreche survived into the present day is unknown.
