Made by the god of labyrinths and puzzles himself, many of his puzzle boxes have been made and sent out throughout the multiverse to habitable worlds. Usually they hide themselves until life on the world they are on are evolved enough to possibly solve them.

Whenever one is solved, an avatar of Halcyon that speaks for the god appears in front of the solver. They are rewarded with a wish and an opportunity to visit or even remain on his home plane. Halcyon is not malicious and loves when someone solves his puzzles.

Not to be confused with The Lament Configuration from Hellraiser. Halcyon's boxes won't send you to hell or send hell priests after you.

Other three sides in the works. If any artists see this and have a puzzle box design in mind, let me know and I'll commission you. They can look like pretty much anything.
