My current work is called The Gladius Brigade and I am writing it in collaboration with my brother. It is a crossover between our original works (Which I had published as "Heroes fanfic") and Splatoon. We have chosen to publish it under his name, so please find it among the works of Edward Squidman. But it is important that you read Timestep Trilogy and We're History first.
It's also important to note that the rules of time travel and causality work differently here than it did in Timestep. In Timestep, it is revealed that time travel can give rise to two separate timelines, whereas for The Gladius Brigade we adopted the time travel rules seen in We're History.
We hope you enjoy our works
