Nicolas Eymerich, inquisitore

A rigid, brilliant inquisitor rises to power in 14th-century Aragon while investigating heresy, pagan revivals, and violent mysteries among Christians, Jews, Muslims, and other outcasts.

In a second thread set in the modern era, a scientist pushes a radical theory about psitroni, mind-energy, and reality, linking human thought to strange physical effects and impossible travel.

A third thread follows a far-future expedition aboard a psitronic spaceship whose mission and destination are unclear. The three strands gradually connect through time, belief, and an unstable understanding of divinity and reality.
