The Shade Isle Campaign
Anarxis of the North is a great black dragon who appeared in the northern regions of Shade Isle about a hundred years ago. He attacked the dwarven kingdom there, driving what few survivors remained to hole up in their southern stronghold at Dämmendell. Now all the lands north of the Durdäs Rapids are known as the Desolation of Anarxis.
The adventuring company has spotted Anarxis precisely once. Very early in their adventuring career, as they traveled through the Lornwood, they spotted a distant speck flying incredibly high overhead. This proved to be the great blackscale himself; Anarxis circled their position a couple of times and then flew back off to the north, ignoring them like ants on the ground.
