Prima Sphaera: Day Zero

  Light, sound, and scents assaulted the pair’s senses. The sensation of dirt and plant-life stroked their skin before they could get any other bearings. Slowly the scents became familiar to those of a forest; the chittering sounds those of its inhabitants; the light a comforting warmth in the slight chill air around them. Each breath was pleasant - the atmosphere very comfortable.
  “A life-” the girl stopped short her attempt at speech, hearing its tone and grimacing as her eyes adjusted and saw the form of her brother. Both her voice and his body were those of a child. She glanced down towards her chest.
  “A life bearing planet. How lucky,” she pouted.
  The boy had a much worse time of it. He understood some things, but was ultimately lost.
  “La...na? Where… why…”
  “Maybe we weren’t that lucky after all,” she frowned deeply. “You don’t remember what happened?”
  “I… I - ugh!”
  He cradled his head as she stroked her palm against the nape of his neck. Eventually some of the pain stopped and he began to glance around. The forest was not particularly familiar. The species of flora and fauna did not immediately register in his memory either - they were clearly somewhere new. Some of the trees nearby had chunks gouged out of them.
  Likely caused by our descent on this time-plane… she thought as he squinted at them.
  “I’m… hungry. How many years has it been since we’ve eaten?”
  “Half of a negative Galan millenia, if I had to hazard a guess.”
  “Since when did Gala become our standard for time measurement?”
  “Since I wasn’t sure how far back your memory has been affected. Thought I’d pick something nice and old.”
  “Negative. Backwards. We’ve regressed?”
  “Our bodies have, anyway. I don’t think we’ve actually jumped to a past timeline this instance. I’m having trouble telling when and where…”
  “This… inst-,” he got out before he quite literally choked on the memories. “R-right. That was quite, quite unpleasant. We should never do that again."
  A few seconds passed in quiet, before his stomach gurgled violently.
  "I’m still hungry.”
  “What do you expect me to do? I’m as naked and at a loss for what is edible on this planet as you are. Just because a creature eats a plant or,” she shivered, “a plant eats a creature doesn’t mean either are safe for our current biology.”
  “I don’t think I care. I’ll adapt or die.”
  “Just calm down, Leyth. We’ll figure it all out. We always have.”
