Hello, while playing the Raven's Purge campaign thanks to my bits of knowledge about the setting lore and the game events I came up with a pseudo-scientific paper written by my half-elf sorcerer regarding the nature of elven rubies and how to harness them to become an immortal creature. Undead and most importantly Liches are my favourite creatures so I always try to find or "create" them in a setting. Let me know what you think.
A huge thanks goes to Per Holmström for his "Long Harbour" adventure site, the role the elves played in it was really inspiring.
