Aidalon was once the busiest hubworld in the galaxy. Then the Collective arrived. Their portal technology connected all worlds, making space travel obsolete. Aidalon's shipyards became scrap yards, yet its people persevered. In the myriad districts of Aidalon, exceptional individuals known as Seekers rise above the throng. Trading in the black market currency known as Shards, Seekers enlist the aid of influential Agents who have the power to help those closest to them, heedless of the Collective's will.

Hubworld: Aidalon is a non-collectible, competitive card game of daring espionage, deduction, and suspense. Take on the role of a Seeker as you navigate the vertical streets of Aidalon, infiltrating your opponent's districts to expand your network of Agents before they can do the same.

Each Seeker is represented by a Seeker card, as well as a 36 card deck you construct. Each deck must contain exactly 6 Agents chosen along with 30 other cards from up to 4 different factions. These cards can be Sources (people and places), Obstacles (traps and barriers), and Moments (one-off abilities and tricks).
To win the game, you must secure 3 Agents from your opponent before they do the same. The first player to secure 3 Agents wins. When playing against multiple opponents, each Agent must come from a different player (if able).
