Strata is the first full-length sourcebook for the cut-throat and brutal Spire RPG system. Two new classes: the purple-prose black-magic pulp fiction occultist Inksmith and the multifaceted and fractured Shadow Agent. Many new extra advances for any class, such as the flower-skinned Druid of the Living Spire, the muckraking Gazetteer, the sigil-scrawling Children of the Runestack and the language-hunting Lexicutioners. Ten scenarios from the original authors of Spire and nine exciting new writers, allowing you to start a campaign of Spire easier than ever. More details on the richest and poorest parts of Spire: the shadowed and fecund Garden District, the decrepit grandeur of Ivory Row, the nightmare industrial bowels of the works, the alien luxury of Amaranth, and more. Beautiful full-page, full-colour illustrations from original Spire artist Adrian Stone throughout.
