The Infinite Corridor

The Infinite Corridor is a strange and ominous location, a space where the Weave of Magic does not reach, and magic is seemingly impossible to use in any form.
Lucien Novelle, Nathaniel Lightheart, and Julius Von Parvel ventured into the Infinite Corridor, led by Alexander Thrawne, who claimed to be one of few people who could gain access to, and travel through it. 
The ancient hero, Aetius, is currently trapped within the confines of the Infinite Corridor.
Thanks to The Oracle, Factus Formis learned that the Infinite Corridor was originally created by Praeteris, but that its current state has been highly corrupted somehow.
