Artifact
One variant of the map contains an area in the lower right hand corner (see the screenshot at right). "Drowning" by falling off the bottom of the map will respawn the player on an otherwise inaccessible ledge further to the right. Falling to the right again will respawn the player at the Enigma artifact. Fall off once more to return to the main area.
