The Titan's Orb is a realistic adventure novel series.

It also crosses over with the Warcraft universe, and various elements from the Far Cry and Fallout universes.

The story is set on Earth from the first person perspective of the protagonist, a self-inserted version of Callum Horncastle himself, with a semi-altered background story.

The plot is set before My Little Pony's third season, a demi-god escapes from Tartarus and destroys Equestria's most valuable artefact, The Titan's Orb, sending it to Earth in the form of six shards. The Orb is the only thing protecting Equestria from outside dimensions, and so the Mane Six are sent to Earth to retrieve it, where they encounter Callum. Agreeing to assist in guiding the ponies in locating the orb, he embarks on the greatest adventure in human history.

To find The Titan's Orb.

Touching on sensitive subjects, such as suicide, death, sexual assault, and various mental health issues, the story has received extremely high praise for it's "Down to Earth" depictions on these subjects, alongside an appraisal for its intricate and well layered plot.
