The fourth story in the Caridoon universe.
This is a direct sequel to Dusk Shine Rising You will need to read that to understand just what is going on. All the warnings that apply to that story are the same here.
Big thanks to Manifest Harmony for giving me permission to do an anthro version of The Clocktower Society and for supplying the cover art.

If Equestria is going to successfully infiltrate Caridoon the volunteers are going to have to be trained and conditioned to pass as natives. Meaning mares need to learn to pass as submissive sex-slaves and stallions need to be believable douche bags. This is not something the army teaches in basic training. Just how can Luna train her cadre of infiltrators? Enter The ClockTower Society. Are they a Caridoon fifth column, or are they the perfect solution to Luna's training needs? And just how is Luna going to react when she finds out that Twilight Sparkle now goes by the name Dusk Shine?

Contains consensual BDSM play, Rule 63, and hopefully a few giggles.
