A shade tree. By which I mean, a tree that continuously spawns Shades.

I asked ChatGPT for funzies and got a wonderful answer.

In the garden of the sinister necromancer, amidst the twilight gloom and labyrinthine pathways, there resides a solitary object that epitomizes the abhorrent nature of its master. It is a ghastly monument to the forbidden arts, an artifact that strikes terror into the hearts of those who dare cast their gaze upon it.

This accursed relic is none other than the Ossuary Chalice, a vessel wrought from the bones of the long-forgotten dead. Its bony surface bears intricate etchings, arcane symbols that pulse with an eldritch glow when touched by moonlight. Within its unhallowed depths, the chalice harbors a malevolent energy, an essence harnessed from the very essence of death itself.

As moonlight casts its pallid sheen upon the garden, the Ossuary Chalice exudes a sickly aura, permeating the air with a scent of decay and despair. Whispers, like spectral echoes, emanate from its depths, murmuring of forgotten realms and the forgotten souls that dwell within.

Within the necromancer's garden, the Ossuary Chalice stands as a grim testament to the depths of depravity and the mastery of forbidden necromantic arts. It serves as a focal point for the necromancer's insidious rituals, drawing upon the forces of the beyond to fuel their dark desires and beckoning forth the restless spirits that haunt the realm of the living.

Beware those who chance upon the garden of this maleficent sorcerer, for the Ossuary Chalice is but a glimpse into the unimaginable horrors that lie dormant within, awaiting the moment when the necromancer's sinister machinations reach their zenith and plunge the world into eternal darkness.
