Bone Nail and 2P Games announced that The Piper of Dawn, a story-focused alchemy workshop management sim set in the sealed Diamond Castle, will launch on Steam on September 23, 2026. The developer is known for Yog-Sothoth's Garden, a bishoujo x Cthulhu Mythos game, and the new title follows a similar style.
The game puts the player in the role of an alchemist managing an underground workshop while other humans work the surface fields. Clearing weeds and crushed stones yields diamonds as starting funds, and the farm offers over 100 crop types with random stats that can be combined for high yield, growth promotion, and auto-watering.
Characters include Akane, a tavern waitress with superhuman strength and a talent for cultivation; Nana, a sharp-witted human-wood manager skilled in combat; and Gretel, a humanoid occult trigger with a large pink-gold tail and overwhelming gun skills. Their stories connect to the secrets of the Diamond Castle, the conflicts of six major factions, and the truth of the recollections, with player choices leading to different endings.
