The story begins with werewolf Caleb Ghatz watching a documentary on a flight en route to Massachusetts where, in accordance with a letter he's received, he and nineteen others will be spending a week at Trinity Heights Suites - a newly-opened resort - as a reward for academic excellence. The documentary states that Trinity Heights was originally a distinguished mental institution before its closure.
Chapter 1: Graham Building
The second chapter of the story mainly concerns itself with introductions. Caleb arrives alongside a flirtatious girl named Elle, as well as a young man who's dubbed himself "Chance". Two other young men, Lenten and Hinoki, arrive shortly afterwards. Some time later, the next group arrives; two females, Ivy Moreau and Rosalind Beauchamp; and two males; Casimir van der Fjord and Theo Letum. This is repeated in Graham Building: Part IV with the introduction of Brennan Reynard, Dana Adams, Calida Wiloka, and Elijah Killian. Upon arrival, many of the guests are taken by the refurbishing of the foyer, though also off-put by the mournful air that hangs around the grounds.
