Chapter 4: Yon is the third portion of Prismeer described in The Wild Beyond the Witchlight. This adventure aims to expand the transition from the three splinter-realms of Prismeer (Hither, Thither, and Yon) to the Palace of Heart’s Desire, highlighting the dense mists that cloak the domain.
Each of the three splinter-realms of Prismeer border the Palace of Heart’s Desire, yet only Amidor, in Chapter 4: Yon, knows how to get to the palace. This adventure introduces a scenario where the mists impede the party from getting to the palace from any splinter-realm, posing an additional obstacle for the party to overcome. The key to undoing these mists rests in a mysterious windmill just north of the Palace of Heart’s Desire, depicted on the map of Prismeer but never described in the Witchlight adventure. The Mill in the Mist expands this new location with exploration, intrigue, and perhaps a bit of combat (or clever ways to avoid it). As always, it is up to you how much of the content you want to use. It’s perfectly fine to use some parts of this supplement while discarding others, or simply let the ideas presented here inspire new ideas of your own. This supplement assumes a party of 4-6 characters of 6th level with scaling options for higher level.
