Check it out! I have a crazy sword and planet short story at StarShipSofa. It’s called the Glorious Tunnels of Our Gravity Dragons. It’s got wyrmholes made by gravity dragons, twin sisters who are hunting and closing illegal portals, and a psychotic princess of mars (with her pet bear, Mister Buttons).

Enjoy!
