From publisher blurb:
Dark Albion Adventures: The Ghost of Jack Cade on London Bridge, is a 22 pages long fantasy RPG adventure for the Dark Albion: The Rose War campaign setting. It is OSR compatible, meaning you can use it with most OSR role-playing games such as Swords & Wizardry, OSRIC, etc., and of course Fantastic Heroes & Witchery by the same author. It could also be used with 5e rather easily (you just would need to adapt six NPC stat-blocks).
This is a low level (i.e. intended for 1st level, probably newly created, characters) introductory adventure, that occurs on London Bridge. This is mostly an investigation adventure, without dungeon crawls (though several buildings may be explored). It would be typically run in a single 4-5 hours gaming session. This adventure will be perfect to set the mood of a Dark Albion campaign.
