Eternal Vessel

Declare a mythic lichdom event tied to a phylactery, forbidden archive, dead city, starved god, immortal spellbook, royal tomb, or soul engine. It can found a necropolis, preserve a bloodline of scholars, make a library deathless, or bind your soul to a legendary vessel. It can be opposed only by Tier 10 lichdom, divine intervention, soul-destroying miracle, or a story condition set when declared.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
