There are sheets for Players -- grunts, vehicles, and spirits are planned.
Spells, Weapons, Matrix Devices, and many other items are supported. Many values are auto-calculated from equipped items (armor, essence, matrix attributes).
Currently no compendium items, waiting for a more stable position before beginning that.
Still work in progress. Message me with feature requests/bug reports.

7th Sea is a tabletop roleplaying game of swashbuckling and intrigue, exploration and adventure, taking place on the continent of Théah, a land of magic and mystery inspired by our own Europe.
Players take on the roles of heroes thrown into global conspiracies and sinister plots, exploring ancient ruins of a race long vanished and protecting the rightful kings and queens of Théah from murderous villains. It is a world of sharp blades and sharp wits, where a cutting retort can be just as deadly as a sword’s point.
