Castle Britannia Blocked and Inaccessable
Delfan (Zapa) of the Kingdom of Dawn was the first to notice something was wrong.
The wayward archaeologist was wandering past the gates of Castle Britannia when he noticed flames pouring from the interior gate. He assumed rioters were responsible, but as he approached, he noticed something more. Castle Britannia has been walled off, conjured flames licking the granite walls.
Further investigation reveals that the Castle is inaccessable through magical means. Mages attempting to enter the Castle are prevented from doing so, as if some sort of barrier has been laid upon the centuries old fortress.
