When the bombs fell in 2016 Lincoln, Lori, Lily were in Chicago visiting the Santiagos. They ended up seeking shelter in the Chicago metro system like many of the local residents. Soon after the initial blasts people realized the surface was no longer safe. They stayed down there and for the next 14 years the metro tunnels turned into small settlements, the last hope for humanity. The radiation mutated hundreds of animals creating new dangers never before seen in this world. With these new threats endangering the last of the human population. It's up to Lincoln help put an end to these dangers Disclaimer I am aware that the Chicago metro is mainly above ground, but there is literally no below ground metro within a hundred mile radius of Royal Woods aka (Royal oak) Michigan. So for all intensive purposes the Chicago metro is completely underground for this story. I'm sorry I tried to find something but there was nothing. Please bear with me, and if it wasn't clear I don't own the loud house characters. Update: I changed the cover to something a little more appropriate. If you're wondering who did the art it was oswaldojimenez11 on dev art if you like it make sure you go check out the rest of his content, it's fantastic.
