"The toxins are now airborne. They say we won't see it, smell it, or be pained by it, only grow tired and sleep. The Flood is upon us, our sensors indicating star roads already opening outside our orbital defenses. We have only hours now. I and two others remain here. Their spouses have joined them. Together we shall shut down the facility and power down our personal ancillas to prevent them from saving us. This is our last act of defiance. The Flood will get nothing from Triniel. We stand united. We fall together. And may our sacrifice, all 883,489,876 of us, from the youngest to the very oldest, be stored and remembered in the sacred halls of the Domain."

— Translation of a final message left behind on Triniel.

Triniel is a planet in the Forerunner ecumene that contained a manufacturing facility for Forerunner ships.

History

At some point in Forerunner history, Triniel was settled as part of the ecumene and became a flourishing world with multiple cities on all three continents and a Builder facility for creating and repairing Forerunner ships. However, during the Forerunner-Flood war, Triniel became a target for the Flood. With no escaping their fate, no help forthcoming and nowhere to run, the planet's population chose to commit mass suicide by releasing a planet-wide toxin that would deprive the Flood of their food source and potential for enormous growth. By the time the Flood arrived, Triniel was a dead world and was thus left untouched by the Flood. Over the next 100,000 years, the toxin dissipated, leaving Triniel's atmosphere safe again. The effects of the toxin likely created a divergent evolutionary path for all of the planet's flora and fauna.

Geography

A planet one and a half times the size of Venezia, the gravity is a little higher than optimal for humans, but not too bad that humans can't operate on its surface. Triniel has azure oceans and three continents of emerald. In the early days of the planet, the long, narrow continents had been a connected series of volcanic mountain ranges that wrapped like a spiral around the planet. In time, the range broke into three pieces, eventually cooled and the volcanic activity slowed, allowing the evolution of a temperate, lush world ripe for colonization. By 2557, Triniel retained a flourishing population marine, mammalian and avian lifeforms including a species of bird that had evolved from the size of small birds to be as big as the Ace of Spades. 343 Guilty Spark theorized that the planet-wide toxin used by the Forerunners to commit mass suicide created a divergent evolutionary path for Triniel's flora and fauna.

Due to Forerunner colonization, Triniel possessed many Forerunner cities and a manufacturing facility for Forerunner ships built into a mountain at the very tip of the central continent.
