• Two new classes: the purple-prose black-magic pulp fiction occultist Inksmith and the multifaceted and fractured Shadow Agent
• 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 (detailed below), 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 artwork from Adrian Stone throughout

The scenarios in Strata are:
