Philosopher's stone

Created by Hazel Ninegate via The Apotheosis Event, it was lost for a time in the multiverse until Hazel recovered it. On February 9th, 2021, The Intern forced her to use the bulk of its power to grant Thrash a new lease on life, giving him uncounted new regenerations. Hazel took the greatly diminished stone back, hoping to use it for her own plans to achieve immortality. After that incident, roughly only 25% was left.
