Here's the Avestan first chapter:
Bold textFirst chapter on Japanese
Quick summaty from 4chan
>20 years have passed since the prologue
>Quinn is now part of Vahman Yast, the core organization of the side of good
>they're in the middle of fighting a Daeva, a powerful evil creature that annihilated most of her squad
>Quinn and Samluch are the only survivors
>Samluch is missing an arm and a leg, but stops Quinn from healing her, only asking her to send her flying
>Samluch then proceeds to tear the Daeva to shreds with her gigantic arms and legs made out of a red aura
>The Daeva is dead, but then starts regenerating despite all the damage it suffered
>It's then blown to bits again by Magsarion emerging out of it Shirou-style
>The whole reason they're stuck fighting it is because they were looking for Magsarion after he didn't respond to the top's orders for him to return to the base
>The Daeva is still regenerating, but Magsarion says he figured it out and they didn't have to interfere
>He then proceeds to blow it to shreds as Quinn loses consciousness from the fall
There is also a lot of setting info thrown around, like Vohu Manah being the guardian star spirit of Vahman Yast that was badly hurt by Forge Dad, but still gives away his feathers so everyone can fly and such.
