Bluebird Jay

Hey there! I'm Jay (He/They), and I'm a TTRPG designer! Thanks for stopping by!

I am the creator of the RUNE System, a deckbuilding-inspired TTRPG ruleset that I used to make Hollow Knight: Masks of Fate!

I've also made some games in the wonderful Caltrop Core, a simple d4-only system created by TitanomachyRPG.

You can find the majority of my 5e homebrew projects on my Ko-fi here!

No classes? No problem! Create 'decks' of abilities that grow as players advance in the RUNE tabletop RPG system!

Venture to lands unknown, wield the powers of great heroes and face new foes in this TTRPG tribute to Hollow Knight!

Bandits have launched an assault on the most popular tavern in town! Too bad its owners are retired adventurers.

Made in the Caltrop Core, battle fellow goblins in an explosive literal-fantasy football tabletop game!
