2018, a dark year for bio-fused engines. Many couldn't escape the hands of HiT Logistics, which had set to erase any sign or evidence of them. The Project G-1 incident would mark the end of bio-fused engines as a whole, as an enraged man, once a bio-fused engine, would tear a man that meant dear to him, in front of his wife and son. Years later, 2038, Sodor would become a pariah state, blockaded from the entirety of the UK. Some engines now have the Mainland as their only hope, but it would be proven difficult for them. One man would be ready, to challenge his own biases against bio-fused engines, in hopes of getting to Sodorland to uncover a sinister plot from the past, while another determined soul, a bio-fused British Railways Standard Class 9F, would challenge the harsh conditions that the world has put on bio-fused engines....

As Sodor has basically gone back to normal, everyone is finally able to rest, however, a darker force then ever is brewing in the background. Join old faces and new faces as everything descends into madness.
