Itza tried to enter the dreaming with John to show him the way she sees the world but some unseen force caused it to go wrong and instead she was flung into a different universe while John was booted back to the universe of ST. Little did she know she was sent to an alternate Warhammer universe where the emperor of mankind was given the ability to talk via a text to speech device. The following is her story there.
Itza appeared with a flash inside an enormous ship. She was inside an eldar craftworld, immediately she was surrounded by guards. She was asked to identify herself and for some odd reason she could understand them. She gave her name and what she was, the guards looked at each other unsure of what to do. They had never had an intruder quite like her so they take her into a holding cell within the ship. She looked at the ship, it was extremely advanced and operated by technology she had not seen before.
She was held in the cell for a few hours before someone came to talk to her. She sees someone in weird dress comes to speak to her. The person speaks “I am farrseer Ylria of the eldar craftworld Biel-tan. Now tell me Iztaccihuatl Xochitl, how did you enter our ship like that? We have never seen this power, teleportation without using the warp.”
“I don’t know myself, all i was trying to do was show John the dreaming” Itza replies
"What is this dreaming?" Ylria asks
"A realm made from human dreams and creativity" Itza says
Ylria thinks for a moment, the person before her appears to be another eldar to her eyes, and as far as she could tell this stranger was not a warp entity. Strangely however is that this ‘Itza’ seemed to have the warp flow through her like a daemon without being one, she wasn’t even marked by any of the chaos gods. Ylria decides to take her under her wing to keep her under observation, find out how she arrived and to see if her connection to the warp could be used in their favor. Ylria leaves to convince the other eldar to allow her to train this newcomer.
