Asem-369 is assigned to use an experimental slip space portal that is capable of transporting a human long distances from one plant to another fast, efficient, and within atmosphere. Using this experimental technology, ONI sent the spartan-ll through the portal to a supposedly Covenant established planet to nuke an 'important' Covenant base. But a malfunction causes the Spartan to teleport out of his assigned pelican to an unknown planet and gets sucked into its atmosphere. With the help of this planets weird inhabitants, he must find a way to get back home. But there might just be more to this planet and he thought.

No matter what happens no matter what case scenario he may be in, there's one thing the Spartan does now:

These ponies for the better or worse. Will change his life forever.

Takes place sometime in season 4
