Inner Tilog has now had its name change in game to Giblot Magnus...
Magnum, actually.
(I didn't realise realms could actually change their names?!)
They can't. But I can, if there's sufficient reason.
In this case, the realm was resolved upon it, they held effectively the same position as Giblot-that-was on the map, and they were willing to sit through the waiting period (and come up with a similar-but-not-exactly-the-same name).
(All of this is using the few precedents set by Tom, chiefly the change of Xinhai to Morek Empire.)
