The Crypt of Nondeskrypt

Ahoy, adventurers! The kingdom of Nondeskrypt needs you! A vile lich has taken residence in an old royal crypt forgotten by all, and it needs to be taken out before it unleashes undead hordes upon the land! Explore the crypt and seek out the old relics of the royal family to help you!

Funny story, I was already working on a DND Ideas set before the announcement of the challenge.

This set contains 2481 pieces, including ones not visible in these renders such as support bricks, technic linkers, and golden weapons hidden in a secret area beneath the throne.

This set contains an elf ranger, a human paladin, a human sorcerer, a demi-goblin rogue, a lich, a ghost, a zombie adventurer, a haunted armor, four skeleton warriors, one chopping skeleton (in pieces in the blade hallway), one royal skeleton, and one hero skeleton (in pieces beneath the throne).

This set contest an undead minotaur, an undead giant snake, a headless centaur, and a bone dragon.

Comes in four detachable areas.
