In the destruction of Skyreach Castle and its devastating return to the surface - the Castle collides into the mountains of Frost Maiden Pass.
The immense impact causes snow and ice to be kicked up into the atmosphere, plunging the Northerly continent of the Elder Expanse into a sudden and permanent state of icy winter.
Since your absence, in the Expanse much has changed.
The history you knew and the landscapes you see are almost unrecognizable:-
The struggle of the changing environment causes friction between the
different groups and factions within the Expanse.
Over time the continent fractions off, many turning their backs on and the realm with their poor support of those in need - in aid of looking after themselves.
The world of the Elder Expanse is changed forever.
Chaos and bitter cold reign supreme.
