In the nightmare, twisting unreality of the Heart that roils relentless beneath the city of Spire, havens are islands of calm - settlements where people have carved out a portion of stability in which to live, work and prosper. This sourcebook gives gamesmasters the tools they need to build a haven together with their player group, ensuring that their characters have a place in the community and that they’re invested in keeping it as safe as possible. At the end of the process, you’ll have a unique landmark with tension, threats and a delicate status quo to maintain – or destroy. In the second part of the book, the ultimate threat to havens - Angels, the fleshy, uncanny emissaries of the Heart Itself - are examined in more detail, with four new varieties ready and waiting to infiltrate, destroy, spy on or overgrow your precious settlement.
