The world of Exandria is in a state of turmoil after the Archmage Ludinus Da'leth took advantage of a magical phenomenon known as the Apogee Solstice to lock the ruddy moon Ruidus in the skies above. Arcane abilities, such as teleportation and communication, have gone offline. Enchantments have unraveled and uncertainty about the future is high. Two members of the adventuring group known as the Mighty Nein, Beauregard Lionett and Caleb Widogast, were part of the teams that attempted to stop Ludinus but failed. Now the Mighty Nein themselves must come back together and aid a world on the brink of chaos, where danger could come from any corner.
