From the developer:
Akkadians, Raging Tiger and King Strom Toad will not wait for you to come to them, they'll be coming to Izvara to rain havoc on the city. From the intel we've gathered they'll be coming every weekend but no one knows exactly what time so keep an eye out for a message from the GMs
