Started in October of 2001 by SLWalker (then going by her married name SLWatson), the Arc of the Wolf began with a full-length novel On the Nature of Wind. The story itself was dedicated to Scotty's days in the Engineering Academy and his journey towards becoming the engineer he would be in later canon. However, due to writer's block, the story sat for many years.
Originally, the novel wasn't meant to have any prequels or sequels, let alone become a story arc, but in 2007 the author caught the proverbial bug again and began writing short stories based around On the Nature of Wind, dealing with the OCs and Scotty himself, taking place throughout the timeline. She also finished the original novel, after extensive editing, and released it over six years after it had been started.
Eventually, there came a time when there needed to be some way to distinguish these stories; hence, they were all collected under the name 'Arc of the Wolf', which spans pretty much Scotty's entire lifetime.
The story arc remains incomplete, but there are currently fifty-one stories by the original author and an additional fifteen stories by eight other authors who contributed to the overall storyline and shares a universe with other authors' storylines.
Taking place primarily in Aberdeen, Scotland, on Earth, Distant Horizons chronicles Scotty's life from age six to age eighteen, wherein he goes into Basic Training for Starfleet Academy. Covered in this timeframe are numerous incidents and events that are later reflected in action or deed. The events, if not the backstory details, of the TOS novel: The Kobayashi Maru, are included in the storyline.
On the Nature of Wind
Taking place primarily at Starfleet Engineering Academy in Belfast, Ireland, Earth, On the Nature of Wind follows the misadventures of fourth-year cadets Montgomery Scott and Andrew Corrigan as they get handed a practical final in Historical Engineering and Design class, leading to a schooner, twenty-four guns, a plot to sink the competition, a storm and a hard choice made and carried through, despite the consequences.
Taking place over the two years after the ending of On the Nature of Wind, True Bearings follows Scotty and Corry as they try to make the best of their respective situations, either apart or together, following their court martial. Taking place primarily in South Bristol, Maine, it touches on many other locale, to include Vulcan, the Lunar Spaceport, and briefly Deneva. Most of the stories, however, take place close to the ground.
