And finally, the Court of Spades! Spades psychic powers support sharp and decisive action, letting Espers create flashes of clarity and assert control. Powers include Hypnosis, City Speaker (my personal favourite), and Cyber Diver.
Three character illustrations. Sir Bedevere, Goofball, and 'Molotov' Mol.

Watch out, it's the Court of Hearts! Hearts psychic powers are all about connecting with others, and letting their thoughts and feelings merge with yours, with miraculous results. Powers include Psi-Jammer, Cryokinesis (got to protect those feelings!), and Telepathy.
Three character illustrations. Psi-Hero Blue, Ms. Cherry Sunday, and Evie Dence.

Three Sails Studios @threesailsstudios.bsky.social · 18/08/2026
Next, the Court of Diamonds! Diamonds psychic powers encourage you to remain firmly grounded and introspective, and to turn knowledge into raw power. Powers include Summoning, Geomancy, and Precognition.
Three character illustrations. Frostbite, Jahan Sulayman, and Maurice Tricotage.

Perfect time for Nathan to be posting this, as I had a sample of the custom City of Espers card deck arrive in the post just this morning! If you're not following City of Espers on Backerkit, get on it! :)

At the start of each session, you draw five cards. These cards are your opportunities, the risks you take, the bad ideas you definitely won’t make, right? When the GM calls for a check, you choose a card to play against the target number, and you might add one of your attributes to the value!

We’ve talked about the narrative side of City of Espers. Now it's time we explored the resolution mechanics! There’s no dice in this game. Just a deck of cards, the luck of the draw, and the choices you make to try and succeed. And did we mention Espers will come with its own custom card deck?

Here are the four Turf spreads for the four 'major' Houses featured in the book: Constellation Cord (House of Starfall); Eye in the Sky (House of Oracle); Nada to Vada (House of Fantabulosa); and Singularity Sector (House of Hyperion). Each one lovingly drawn by Shane Melisse.

I got to write two Turf entries in the City of Espers rulebook: Open City, the Turf of the House of Barricade (can you smell roses and gunpowder? It's near!) and Joyous Gard, the Turf of the House of Avalon. Let's dive into the latter. Here it is in the book, complete with text.

You know when a TTRPG has a mechanic you'll ride or die for? That thing that you will always tell people about? The thing that makes that game THAT game? For me, @theneoncaster.bsky.social made one for City of Espers. It's the main thing that made me want us to publish it. Let's talk Turf!

But you don’t have to use one of the Houses in the game book, one of the best bits of the game is creating your own House and Turf. What sort of House do you reckon you’d bring to Zener city? Don't forget to pre-save the Backerkit: tinyurl.com/ynrc6e3d

When a House has forged a strong enough connection, they may develop Turf, a psychic awakening of the city with its own personality & powers. Fantabulosa's Turf is small, just a few blocks from the theatre where people on the run from something supernaturally find their way onto its streets.

Houses have pre-existing characters to bring into your games, and Fantabulosa is no different! The contortionist Ducky, the magician Riah and the right hand ma’am Doreen make up some of the Espers found here. And perhaps most importantly is Bijou, Mr Measures son who is set to take over soon!

The House of Fantabulosa put on vibrant and saucy shows, thanks to their decades of musical, burlesque and circus skills. Led by the Pearly King, Mr Measures, this musical hall impresario started Fantabulosa to provide a safe haven from the prejudices elsewhere in Zener and beyond.

In CITY OF ESPERS, your characters are part of a House, a group of bonded Espers who work together! Some have existed for years, others are brand new and just developing! Let’s take a closer look at one of these as an example, the House of Fantabulosa. Pre-save the Backerkit: tinyurl.com/ynrc6e3d
