Human habitation on Pern stretches back well over 3000 turns, and numerous cataclysms and upheavals have occurred over that time period. It should be little surprise that much of Pernese history has been lost or muddled.

Igen was the fourth Weyr settled (after Fort, Benden and Reaches, before Ista and Telgar), during the 1st Interval. As it was founded during the winter, its Founding Day is celebrated in that season. Until the founding of Ista and Telgar, its range was one of the largest; now, it is comfortably proportional to the optimum number of dragons the Weyr can house.

Like every Weyr, Igen has seen its share of glory days and painful periods over its lengthy history.


10th Interval
  • Interval 29: The Great Comet strikes Pern. One of the places struck by the debris was Igen Weyr. The impact caved in large chunks of the original inner cavern warren, killed the then-Senior Weyrwoman, and created the crater that would become the modern Crater Lake.
11th Interval
  • Interval 186: Igen suffers a plague that further whittles down an already small dragon population. Over the next ten turns, due to mismanagement, ill-fortune, and sabotage, the Weyr's fortunes go into sharp decline.
  • Interval 197: The events of the RebootTP occur. After 10th Interval HRW's Senior Weyrwoman, Rhaeyn, accidentally mistimes it to 11th Interval Igen, she discovers that her own time was on the brink of a devastating comet impact. This ultimately culminates in hundreds of people from the 10th Interval coming forward to the 11th Interval to escape the destruction and assist the undermanned Weyr with the coming Pass.
  • Interval 198:
    • The Battle of the Queens occurs. Oldtimer Jivayath and Nowtimer Kohleth rise at the same time, leading to significant injuries to the aged Nowtimer. After Kohleth lays a small clutch, Vergora is confirmed as continuing Weyrwoman, with N'thu as her Weyrleader… but as the injured dragon's health declines, it becomes clear that this status is temporary.
    • After an abandoned Weyr is discovered on the jungles, a contingent of Igen riders breaks off to establish a new home: Southern Weyr.
    • Weyrlingmaster O'oc is murdered. Suspicion initially rests on Br'er, but eventually comes to rest on HRW's Weyrlingmaster. Igen's leadership learns to step very, very lightly with the other Northern Weyrs.
  • Interval 199:
    • Kohleth dies, just a few scant days before her joint clutch with Jivayath hatches.
    • PC Clutch 1 hatches
    • Corelle of Telgar is transferred to Igen, and gold Ofrovth rises, establishing Corelle and W'rin as Igen's new leadership. The Weyr's politics start to lean towards Nowtimer mores, to the dissatisfaction of many Oldtimers. Corelle allows guard raids in the Bazaar that turn many of the Nowtimers against her.
    • NPC Clutch 1 hatches. Meddling from multiple Oldtimer riders (including Corelle's juniors) results in several girls out on the Sands, in direct defiance of the Senior Weyrwoman's orders.
    • Tuli's Elicheritath rises and clutches.
    • Corelle is mysteriously poisoned. Though the poison was delivered by dragonless and insane Vergora, many in the Weyr believe the plot to have originated in the Bazaar.
    • NPC Clutch 2 hatches.
    • Jivayath rises, officially establishing Sadaiya as the new Igen Weyrwoman. W'rin stays on as Weyrleader.
    • Arroyo Wing is mysteriously handed over to Trek: an Oldtimer woman and a bluerider. As W'rin has previously clearly stated he won't allow blue/green wingleaders, this comes as something of a shock to the Weyr. Arroyo soon establishes itself as the 'progressive' wing, in contrast and competition with the 'traditional' wing Whirlwind.
    • An early Threadfall spoils a Keroon gather, giving Igen its first taste of Thread.
    • NPC Clutch 3 hatches.
12th Pass
  • Turn 16:
    • Rajakhelath is caught by Divale's Lukoith, a third clutch sired by the Parhelion brown. The resulting clutch (NPC clutch 18) of twenty eggs hatched nineteen, plus one unhatched which was later carried ::between::. It is thought that a combination of the conditions from Rajakhelath's flight — a sandstorm and a number of injuries — and the brown sire resulted in both the small clutch size and the dud egg.
    • Ione and gold Niatskivhiath transfer back to Igen at Diem's encouragement.
    • Green Oriahysciath is injured in Threadfall, leaving rider Eala to turn the Parhelion Wingleader knot over to Divale until her dragon is able to fly again.
    • Zsaviranth rises in a timely Leadership flight and is caught by brown Rhovvth, making K'vre Igen's new Weyrleader.
        • Simultaneously, the explosions that kick off the Stone Broke TP occur, leaving the Headwoman and Weyrminer to handle things until they're able to get the Weyrleadership on board.
    • Within days of Zsaviranth, Rajakhelath takes to the skies unexpectedly, not very long at all after her most recent clutch's hatching, and is caught by bronze Czhaevth. This adds foreigner Sa'mael to Igen's population, albeit maybe temporarily.
