The sight of what was clearly a private Teleportation Circle caused Hal to raise an eyebrow.
The prospect was not exactly impossible, as Hal himself had a private Teleportation circle in Sapphire city although that circle was limited in its range.
Anyway, having a private Teleportation circle was very much plausible but usually was owned by large families because of the sheer amount of maintenance and manpower that was needed to build and maintain it.
Families like the Doxons and other Duchy rulers, while possessing private Teleportation circles of their own, would hardly need one since the power that they wield makes it so that every teleportation Circle in their Duchy was already theirs to use as they deem fit.
Even the Danes treat the Teleportation circles all over the Silva Duchy capital as though they were their property which is understandable as they were previous rulers of the kingdom that had now become a Duchy.
