Being a creature born of science makes one naturally curious about things that are unknown. Being naturally curious even before his genetic modification, Dusk Rider decides to try and find more information about the demon Tirek, though this requires that he venture through the treacherous Everfree forest, foolishly unarmed.

Dusk Rider is a new test subject from Equestria's biological testing laboratories. A dragon/pony hybrid proficient in all weapons as well as defying physics and reason, he is sent on his first deployment to destroy a griffon base in the midst of a long war between pony and griffon kind.
