Book One

The Solari Ignition

The Isindur Protocols  ·  Series

John Penrose spent twenty-two years in the Fleet Air Arm and fifteen more as a contractor engineer. Retired to a small Cortijo in Andalusia, he was not looking for purpose. He was fixing a solar inverter when his quiet life ended.

Earth sits on the rim of a galaxy it knows nothing about. Older civilisations have been watching it for a very long time. It is far older than Earth's recorded history. Its war with the Veridians is only fifty years old. And now the Veridians have returned.

They don't invade. They shape. Then they harvest.

The Solari Ignition is written in the British tradition — dry, precise, and grounded in the working language of people who get things done.

From the opening chapter

The solar inverter gave a pitiful little click and died.

Again! John stood in the dust of his driveway and stared at the blue box on the side of his old Cortijo.

He didn't curse.

After twenty-two years in the Royal Navy, he'd learned the hard way, that swearing at machinery made him feel better, but it didn't fix it.

He wiped his brow with the back of his tanned, wrinkled hand. At sixty-seven, the Spanish sun felt hotter than he remembered from his tours in the Middle East.

As usual, his joints screamed in protest whenever he moved quickly or put in a long day's work in the campo. It was a painful sign of both an active life and the fall he’d taken in his younger days.

“OK,” he muttered, his voice gravelly from a morning of silence. “You want to play it that way, do you?”

— The Solari Ignition, Chapter One

The World

A galaxy shaped over generations

Eldron

A fortress world of an older human branch. It is far older than Earth's recorded history. Its war with the Veridians is only fifty years old. Earth, on the rim, has been kept unaware deliberately.

The Veridians

They are not a fleet. They are a civilisation that operates on generational timescales. They don't invade. They survey, shape from within, then harvest. The first Eldron attack fifty years ago was a survey.

The Isindur

Largely absent from these events, but their work is everywhere. They seeded twelve human worlds across the galaxy. Earth is the youngest, and least developed, by design.

The Alliance

Three human worlds. Saurian warriors. Sentient AIs integrated into ancient warships. A former Royal Navy engineer given authority over technology older than human civilisation.

The Custodian

One person holds authority over all Isindur technology. Not a general, not a politician. The role was designed that way. The reasons become clear when the technology is understood.

The Sentiences

The AIs of the Isindur fleet are not tools. They are colleagues — bound by the same compact, carrying the same weight. They can see further than any human. What it is for, they cannot say.
