For once in my life, meticulous world building has saved me a ton of time.
I started this series circa 2006-07. I created an impact event in the past that destroys most of the human race; in my series, there are about 17k people left on Earth–and they live in this sort of steampunk-ish world where portions of old tech are utilized to get things done in straightforward ways. I Digress. The impact event involved meteor (7341) 1991 vk, one of those asteroids that love getting too close to Earth every time they come around.
Lo and behold, as 2017 draws to a close, meteor (7341) 1991 vk has come and gone. My impact event cannot occur unless I’m writing one of those alt-history origin stories and I’m not interested in doing that. I must alter my timeline by five years (when vk returns to us), and that’s okay because I’m missing exactly five years in a later portion of my timeline. Nothing happens in those five years that’s relevant to anything in my current series. No dialogue mentions, no visits to places that need brief intros in the narrative. You get the idea.
One thing that did happen that worked amazingly to my advantage was the discovery of the volcanic field in Western Antarctica. My fictional “valley of volcanoes” set off by the altered magnetic fields of the moon’s shift, and the subsequent impact event, melt the Western Antarctic Ice Sheet in my series, creating a place called the Antarctica West Islands. It’s where 23rd-century humanity partakes in trade and diplomacy with the femmar.
Crisis averted. The chain of events that set off the world of my current storyline begins in 2022, not 2017, and that required minor edits to the timeline. I will have to go in and make changes to various Bible-Entries, but that’s a weekend project. ((>_<))
The glaciers in East Antarctica are still intact; this is a subglacial map.
The cities are not just beneath the ice, they’re on the oceanic floor.
