If you can think in seven-plus dimensions, you can visualize the Realm. It is a space of magic and mind-bending physics. The past loops around the future. Portals collapse distance (if you can afford them). New worlds are discovered and settled on the frontier.
A frontier portal – not every new planet or moon can afford one.
A journey can take a year, but that includes several stops. The distance between spaceports is seldom more than a month’s travel.
