Xor 'Vozamai, a Sangheili in the faction Swords of Sanghelios, wakes up in a dark cavern with no memory of how he got there. He quickly finds out that he isn't anywhere near anything that's familiar. As time passes, he starts to remember what happened, bit by bit. The more he remembers, the more he realizes he has to get back home...before it's too late.

This takes place right after Halo 5. But I basically made most of the storyline in the game irrelevant. Oops.
The 'Other Character' tag is being used because of the character tag limit. Other characters include: Sunburst, Tempest Shadow, and Starlight Glimmer so far.
Cover art is final(?). Previously named as Halo: Heroes and Monsters.
