| Age of Wardens Era | 0–400 | The Vale | The surviving Wardens consolidated their rule after the First Age. Their domains increasingly separated into distinct cultures, philosophies, banners, and political blocs. The Heirs passed from the authority of one King into competing Warden societies. |
| First Shaping Era | 400–1,000 | The Vale | Reshaping and Bioweaving transformed Warden civilization. Elves, Dwarves, Halflings, Dragons, and numerous early created peoples emerged as the Wardens increasingly treated life itself as something to redesign. |
| Great Banners Era | 1,000–1,500 | The Vale | The great factions matured. Imperial and Alliance identities hardened, frontier societies developed, the Virborne became a major force, and centuries of territorial pressure prepared the Vale for its first truly catastrophic Warden war. |
| Great Siege Era | 1,500–1,600 | The Vale | The Alliance launched the Great Siege. The Empire survived, but Warden casualties were unprecedented; their numbers fell from thousands to estimates below one hundred. Azure Guard independence and the recognizable eight-domain political order emerged from the aftermath. |
| Great Expansion Era | 1,600–2,200 | Riftmoor | The surviving factions expanded beyond the Vale and across Riftmoor. Continents became new heartlands, frontiers, ports, fortresses, and contested territories, extending the ancient struggle for the Throne across the entire planet. |
| Second Shaping Era | 2,200–2,700 | Riftmoor | The military lessons of the Great Siege triggered another Bioweaving arms race. Giants, Gnomes, Merfolk, Minotaurs, Centaurs, Beastfolk, and many other later peoples appeared as factions sought biological advantages against their rivals. |
| Early Reach Era | 2,700–3,000 | Riftmoor → nearby moons | Vord’s Star Arks carried Kelek and Eleos to Riftmoor’s moons. Asteroid mining and interplanetary freight developed to supply them, while Kelek and Eleos pioneered artificial atmospheres and water cycles. Permanent settlement beyond Riftmoor became possible. |
| Terraforming Race Era | 3,000–3,700 | The Reach | Paith expanded planetary engineering; Zurn developed thermal regulation; Arzu and Medu solved self-sustaining ecological seeding. Rival civilizations stole and combined one another’s discoveries until stable terraformed worlds became reproducible. |
| Expansion of the Reach Era | 3,700–4,200 | The Reach | Colonies, asteroid industries, trade routes, piracy, and permanent military positions spread throughout the system. Vord pushed into the distant Outer Reach, while the system increasingly divided into Alliance inner worlds and Imperial outer worlds around contested Riftmoor. |
| Terraforming of Arzad Era | 4,200–4,300 | The Reach | Arzu undertook the most ambitious planetary-engineering project yet attempted, deliberately using impacts to collapse subterranean voids, alter mass distribution, and stabilize an otherwise unusable planet before beginning conventional terraforming. |
| Battle for Arzad Era | 4,300–4,320 | Arzad | The Empire attacked the newly valuable world. Zurn drew Kelek away and died fighting him, while Arzu killed Eleos and Vord before Kelek escaped. The deaths of three major Wardens in one battle permanently altered the balance of the Reach. |
| Wars of Arzad Era | 4,320–5,000 | The Reach | Arzad became a permanent contested world of fortifications, occupations, blockades, and shifting borders. The broader Reach matured into an established interplanetary civilization whose political geography was increasingly governed by planetary position and orbital alignment. |
| First Jump Era | 5,000–5,050 | The Reach | During an attack on a Vah-Yu ark, Hep and her Wardens accidentally discovered that compressing space ahead of a vessel while displacing it behind could produce an instantaneous jump across enormous distance. |
| Warp Revolution Era | 5,050–5,300 | Reach → nearby stars | Vah-Yu refinement turned the accident into reliable Warden warp travel. Orbital alignment ceased to be an insurmountable strategic barrier, and the technique rapidly spread among all Warden civilizations. |
| Interstellar Expansion Era | 5,300–6,700 | Nearby stars → galactic arm | The Wardens began settling nearby systems and then progressively more distant stars. Worlds beyond the Reach often proved easier to terraform than its difficult original planets, accelerating settlement and allowing every faction to establish new worlds, sanctuaries, and colonial populations. |
| Warden ______ Era | 6,700–7,200 | ~33 million ly² | Warden civilization reached roughly 150 settled or terraformed systems distributed across an approximately 33-million-square-light-year portion of one galactic arm. Distant homeworlds and regional powers flourished, but all remained ultimately subordinate to the ancient contest centered on Riftmoor and the Throne. |
| Late Second Age Era | 7,200–7,500 | Mature interstellar civilization | Warden civilization existed at its greatest geographic extent. The Vale remained its ancestral battlefield, Riftmoor its political center, the Reach its ancient interplanetary heartland, and the stellar colonies its vast outer civilization. This was the world that ultimately collapsed with the Vanishing, ending the Second Age. |
