Race Sphinx Planeswalker
Birthplace Esper, Alara
Lifetime Unknown

The sphinx Crucius is a controversial figure in the history of Alaran Esper. He is a planeswalker.[1]


Decades before the Conflux, Crucius devised the magical alloy etherium and began a grand project to infuse living things on Esper with it. Crucius proposed this Noble Work as a means to overcome the frailties and limitations of the mortal flesh, but he may also have perceived Esper's disconnection from two crucial elements, red and green mana. Indeed, the aether inside etherium may have been intended to enable a spell that would reunify Esper with the other shards.

The Ethersworn blamed Crucius for etherium abominations called aether-liches, terrible creatures who resulted from an over-application of etherium and Crucius disappeared, considered to be an enemy of the plane. Esperites believe him to be in hiding, or dead. In truth, he may have left Alara altogether.[2]

His lover on Esper was Sharuum and they had a son named Kemuel.

Crucius supposedly created the Great Desert, Crystal Labyrinth, and Riddle Gate on Esper as a test to find the Seeker.[3] It is likely that he was also the creator of the Metal Island.[3]
