Mirror universe

The Mirror Universe, also known as parallel universe, is the closest universe in the Alach Theory of Multiverse. It is similar to the Prime Universe in all aspects, with a timeline of its own and people who are considered alternate versions of the ones known in the Prime Universe. It is also known for its dystopian reality, which has caused many of the people die or simply haven't been born or with roles given to another people. Taren's study of the multiverse based on the Alach Theory has allowed him to create forms of travel between universes, being the Mirror Universe the first successful attempt for its relatively stable connection, although the very first one missed the target time window, bringing Taren to a couple weeks before the desired moment.

Sarah has once visited the Mirror universe through a modified dream pod, allowing her to project her mind over the consciousness of her alternate self in that universe, Astrid Fairlight. After getting used to the physical differences, she would then explore this new universe. The humanity has become extremely xenophobic and their nature has shown itself as an antithesis of what Sarah knew. A ruthless, untrustful and self destructive people, where strength was valued more than compassion. Be "human" had a totally different meaning there, and she saw the Mentali Resistance fight the humanity every single day but never to see an end. Her people, the dragons, were extinct as well, being Astrid a winged Blazing Mentali with Lux and Blitz as secondary elements and a snow white fur, very different from Sarah's usual self, a Water Dragon of blue skin.

Taren detected he has an alternate self of his own in the Mirror universe as well, to where he would project his mind over the consciousness. However, Alyssa couldn't find hers, hinting her alternate self would be dead or wasn't even born.
