The Cascadian Isles

Home to the truly ancient Acaethi, the Cascadian Isles were a place of tropical islands adrift on a turbulent ocean.

Climate
The deeper one sailed into the isles, the more strange they would find the landscape. Tropical islands would give way into frozen seas and mists so dense that even on a windy night one couldn't see the stars.

To describe the Climate of the Cascadian Isles is difficult, for much of its grandeur lie beneath the waves in tropical reefs and volcanic chains that span between globe-like cities of the Ancient and culturally disparate Acaethi.

Fauna of the Isles is vaguely similar to stories of what one might find in the Shadowfell in terms of size. Water dwelling mammals could topple galleons, while some herbivores who grazed on jungle fauna could tower high over even the tallest Imperial structures.

History
The Isles has a complex history, for the once chronicled Acaethi had largely abandoned their histories in search of a new culture sometime in the mythic era.

What can be said, however, is that Acaethi structures can be found so unfathomably deep within pitch black waters that the building of them was originally thought to be attributed to some other species entirely. These structures were described as being wrought of an oily black stone, some of the largest of which would dwarf even Aetheron in terms of sheer size alone.

The Isles were home to wars fought between the Aeytheri and Acaethi in the mythic era, though the reason why was lost in the burning of Aetheron.

During the Third Era, the Isles would be ventured into by the Empire under the leadership of Trajan II, though nearly all settlements found within would become strangely abandoned over time.

The Isles were an important geographic half-way point between Erebus and the (unnamed) Esterlands.

The flood that ended the Third Era would cause the loss of contact with any remaining Imperial Settlements on the Isles, and whether or not the Isles still even exist is unknown.
