The Descent

Up in the far northern reaches of Equestria, lies a school. Frostvale Academy. It's no place where commonfolk can enter. Only the brightest of the brightest get an invitation to join Equestria's elite. From Necromancers and fabled weaponsmiths, to living statues and robots. Within it's massive towers sit hundreds of students, on the constant quest of obtaining more information about everything ever to exist.

One of these students is a light pink mare named Ametrine Glow, a famous clocksmith, jewelcrafter, and engineer who now bides her time creating clockwork creatures. Her only friend at the academy, a pyromancer by the name of Burning Bridges, had known her since foalhood. Due to a magical mishap that nearly ended his scholarship, the outer halves of his mane and tail are permanently on fire.

Recently, a massive trench had been discovered in a faraway part of the sea. Ever since it's discovery, Frostvale had been planning an expedition to the trench. It's a long ride by boat, and the ride is bumpy at best. Both Ametrine and Burning had signed up as volunteers - An idea not well thought out.
