The forces of good magic eventually forced the Morlocks through the Gate of the Underworld, with Leanbow personally taking on Morticon at one point. In order to keep the forces of darkness from escaping the Underworld, he held back the Morlock hordes from the Gate while Niella, the Gatekeeper, sealed both it and Leanbow into the Underworld. In this single act, Leanbow would be lost to the forces of darkness and Niella would use up the rest of her powers as the Gatekeeper, giving up her life force in the process.
