They were Winged Lions!
Two dozen Mages were already in position under the Silver Union Mage's organization, silently waiting for the arrival of the Winged Lions.
The Silver Union used this flight path once every fifteen days. They knew very well what race and grade of magical creatures would appear at which areas. Other than situations where extremely dangerous creatures were migrating, or when the creatures of the black forest were falling into a riot, the path was a safe one.
However, there were always exceptions, especially within the black forest, where no one could estimate the danger lurking within. Unknown terrors were always lying in wait.
Powerful magical creatures would usually own a large territory of their own. They were the only kings within this territory and they would never allow other creatures with similar strength to enter their territory or hunt within it.
