Set sails upon the wider world, conquer the waves of the Great Lake and beyond!

The Unofficial Sea of Sorrow is a homebrew rulebook for the Unofficial Hollow Knight RPG to operate and create ship-campaigns and underwater adventures. Players and Game-Master alike are given tools to make their own ships called Leafers and set sails upon the great waters of their world's campaign.

Within this rulebook you will find:

• A ship building and customization options allowing an entire crew of bugs to venture outwards to far away places.
• An intense boarding and ship management system engaging the entire team to play together and to their strength to allow victory over the sea!
• Simple yet in-depth naval battle rules allowing the party to express themselves across their adventures.
• Both detailed and abstract ship map mechanics to allow both hyperfixated bugs and easygoing bugs to have an enjoyable time cruising and pirating!
