From publisher blurb:
Rain of Mercy is an entertaining introduction to the grim darkness of the 41st Millennium and Warhammer 40,000 Roleplay: Wrath & Glory. The booklet — originally only available as part of Free RPG Day — is a short primer on the world of Warhammer 40,000, the glorious Imperium and its many foes, and the forsaken Gilead System trapped by the Great Rift. It also includes an action-packed adventure using simplified game rules so you can start playing immediately.
Rumours abound in the shrine world of an Imperial Saint emerging majestically from the wretched conditions of Holy Enoch’s appalling refugee camps. Can you navigate a treacherous town run by water-selling gangs? Is the Saint a pious vessel for the Emperor’s will, or a perfidious Psyker manipulating the populace?
Employed as judge, jury, and executioner by the Imperium’s representatives on a troubled world fraught with danger and wracked by the Great Rift’s malignant forces — what choices will you and your party make in these perilous conditions?
