@Hoss @eisai Yeah, but you can guess from the clues. EP2 shows that Eli's rocket was launched to somewhere in European part of Russia. The Mi-8 Alyx wants to use to find Borealis has a range of about 1600 kilometers, so it's safe to assume that White Forest is somewhere in Northwestern Russia if Borealis is to be found somewhere around Arctic archipelagos like Svalbard or Novaya Zemlya.
