Breaking of Arcadia

1500 years Arcadia suffered a disaster. The consensus by scholars is that it was cause by the gods to punish the corruption of the temples. Specific allegations against the temples was the lavish way they spent gold upon themselves, punishing people by trapping them within the Orb of Imprisonment without due process.

To the people of Solum, Arcadia is known as a cursed place because of this event.

Known events involved in this cataclysm:
The creation of the canals of Arcadia, that became the borders of Eridon, Mistrya and Sylvas.

Brimstone the Fire Incarnate became trapped under the Volcano on Embershore.

The sinking of the Talens, killing the local population.

The freezing of Caldonia.

The creation of the Shadow Mountains south of Shirebrook.

Trellis had a vision of the day of the cataclym, as viewed from inside a Pyramid Temple to Tempos on Leech Island, West of Akuba. She first saw an earthquake, then the clerics and priests of the temple were attacked by a mist creature with a face that turned into a vampiric mist. (Seaborn 3:6)

At the Caldonian Velmontarious Monastery, 50 frozen corpses were frozen in place, fleeing the temple. Within the temple the monks prayed to their god, asking why they were forsaken. (Seaborn 4:7)

Also in Caldonia, in the protected Salt Port Salt Mine, a preserved journal detailed the days after the cataclysm, that anything leaving the mine would flash freeze, and it appeared suddenly. Frozen Frontier 11
