   Summary

   After exploring a Forerunner station, the Master Chief, along with a combined fleet of the UNSC and the Swords of Sanghelios, ends up in the Mass Effect universe. Unfortunately for the Master Chief, he was separated from his team and ended up on a station full of scum and villainy. Luckily for him, though, he ended up saving a quite talented Quarian engineer who was quite knowledgeable about where they were. Now, can he find his way back to his Fleet with the help of his new Ally, or will he be lost forever?
