Two future's bound

This Fanfiction follows the story of Arthur and Caera going back in time, (The same premise as a clash between times)Of course I'm not going to copy and paste ideas from that, I know I am a rat but I'm not that much of a rat. I asked for permission from Ironswordsman to do this. Like how there are tons of twin brother fanfictions, there the same idea, but all go different paths on how the characters develop. In this Fanfiction, Arthur doesn’t carry as many feelings for Tess as he did in the original LN, but they still had their promise at the wall. Arthur warms up to Caera a bit more than he did in the original TBATE LN. Once they return in time they will merge with their old bodies at the age of nine for Caera and Arthur eight years and ten months. Caera’s body gets brought to Dicathen because of the Pendulum clock that brought them back, It linked them together, making them need to be a certain distance from each other at all times. This distance isn’t short nor is it long, they can be about 10 kilometres away from each other, anytime they try to get farther, their body is unable to move anymore. (Like when you’re playing a multiplayer game on your Xbox and you can only go a certain distance from player one)
