The Dreaming Dark Invades Sarlona

Population Migration / Travel

"When Il-Lashvatar sent his minions forth into Eberron, they began to conquer and lay siege to Sarlona, humans were forced out, but it was the Kalashtar they hunted for. The Path of Light from this point onward would be hounded by the dreaming in the dark"
Ishara-Coratash, Kalashtar

Quori begin conquest of Sarlona, this causes a migration of Humans from Sarlona to Khorvaire to escape the new conquering force. Kalashtar escape from Sarlona as well, but Adar remains under threat.
