TLDR: The Witcher's Realms is asleep but not dead.
Development for The Witcher's Realms is paused indefinitely. I might still sneak in a compatch for CK3 1.12, and I do hope to come back to the mod sooner rather than later. However, the cycle of compatches and development can be frustrating, and with other priorities eating up time, I don't see a path forward for the mod over the next few months. I plan on unlisting the mod on Steam so that it's still accessible with a link, and doing something similar for ModDB. If you're interested in doing something more or less ambitious with the mod's files, feel free to DM. Thank you to everyone who has played, streamed, or contributed to the mod. It's been a fun project, and I'm just bummed to leave it unfinished for now.
Until the next update, va fáill and good luck on the Path!
