Fate\Stay Night X Soul Worker Crossover Challenge

A bored Zelretch decides to play a prank on a Shirou from the Kaleidoscope and warp him to an alternate version of his world. Unfortunately, the warp 'malfunctions' and Shirou is thrown into a completely different reality. After waking up in the new reality, Shirou wanders around looking for answers. He is then attacked by a strange grey wolf-like creature only to be rescued by a group of survivors called the Starry Forest League. He is then taken to Rocco Town where he learns about the Great Void, Soul Forcers, Bashai and Soul Workers. Will the King of Fakers be able to survive in this new, hellish world?

NB:

Soul Weapons are what they say they are. So it will be impossible for Shirou to trace them.

You can choose between Fate, Unlimited Blade Works (UBW) or Heaven's Feel Shirou.

Due to Gaia not existing or having a very weak influence, Shirou's traced Noble Phantasms are a lot stronger than in the Nasuverse.

It is hinted that the only reason Shirou cannot trace EX Noble Phantasms is because UBW could not comprehend it at the time. So it may be possible that EMIYA can trace EX Noble Phantasms. (Not sure how accurate this info is)

Pairings are of your choice Shirou can be paired with an OC, a Soul Forcer, Soul Worker or even a Bashai.

OPTIONAL- Shirou can have a Soul Weapon.
