For all older wolves [6+ years] that I have retired and intend to keep until natural passing. All mentors. At the end of their time, they must journey to the thickest part of the forest, to an old and dead hollow Oak tree that all wolves must pass through to pass into the undead lands. When they have passed through the old tree, they find themselves walking out of the living realm - amidst the almost suffocating, dense blue fog - to find their old pack members, waiting to greet them below the gentle stars. Finally, they can rest.
