Trollhunters: Eclipse Rising

You're from the real world, where Trollhunters is just a show you watched. One night you wake up under the bridge by the Arcadia canal, the same spot where Jim Lake Jr. found the Amulet of Daylight. It's glowing in his hand, and a second amulet lies at your feet. It's dark and blood-red, and it's whispering "Eclipse." Nobody, troll or human, knows what it is. You know how the story goes, but this one isn't going the way you remember.
