After reaching the Vogel border with Veora Kingdom, Minos said goodbye to his men at that border post and immediately opened a wormhole to cross the border of that state.
Once again, he was entering the Western region with the intention of hiding his movements. So he chose to jump the border of this place with his state to prevent possible local observers from noticing him moving.
Minos was still being watched by powers from various parts of the continent, including the Eastern Empire. But given his current abilities and the presence of a well-developed wormhole network of the Black Plain Empire, following or tracking his movements had become impossible.
At most, someone could keep an eye on whether he was in his state's capital or check his passage through other locations in his domains. But if he wanted to venture into the Spiritual World, reaching him now would be much more difficult.
