From publisher blurb:
Either intentionally or unintentionally, the party has teleported to the mysterious Ebonpeak Isle, home of the most prestigious magical academy of the Known World. To their surprise, however, they find the island floating through the Temporal Plane!
To return home, the party will need to solve the mystery of what happened to Ebonpeak Isle. But beware: Kytheros, Lord of Time, has sent an army of celestial monitors to purge his domain of mortal intruders!
Can the adventurers make it back to the Material Plane before time runs out? Assuming time still exists when they’re done…
