Brude

Brude is a Pict Druid and Drust's twin brother. He was the human who helped create the tunnel between the Human universe and the Demonata universe in ancient Ireland during the events of Bec to order to destroy the invading Christians, whom he despised.

In order to open the tunnel, his body had to become part of it's core and so he fused with the stone of the cave.

He was killed when the Lodestone was destroyed.
