Divine Continent: Local Reality
After arriving at a local port, Minos registered his yacht at border control, where he paid a high fee for his and Starclaw's entry, as well as his yacht's stay there at a pier.
After leaving a few thousand high-grade crystals at that post of the imperial guard in Grinia, Minos, and Starclaw got their permits to enter the continent.
Such a thing served for them to have a method of justifying their entry into this place and discounts if they were to move to other empires.
Upon arriving on the Divine Continent, one must pay a fee equivalent to one's cultivation level to access that territory. But when moving internally on the continent, from one state to another, there were also fees to pay.
If one didn't have their entry ID, they could be arrested and penalized with fines and risked having to again pay the entry fee when passing through the local borders.
