I've been in talks with SpiritsOfTheWorld who has decided they want to write the sequel to this story, which they've titled The Assassin of Olympus: Armageddon. They've bounced a lot of great ideas off of me and developed a solid vision of where it's going to go. I'm beta reading for the story and helping them out, but all the writing and story-telling is solely credited to them.
The first chapter is up now: s/13825641/1/The-Assassin-Of-Olympus-The-Armageddon (FF dot net doesn't like links, so just type/copy-paste that at the end of the fanfiction dot net URL. Alternatively, you can just search for the story title in this website's search function.)
