Thurdan was never the one to take the easy way through life. He had stood to gain a lot just by keeping his feet firmly planted at the peak of Anviltop Mountain, his clan's ancestral home. It should have been easy enough, Dwarves were famous for their sturdy stances after all. Not to mention being the heir apparent to lead his clan set him up for a life of greatness. Just the kind of life Thurdan hungered for... except he wanted it by his own achievements and not by birthright.
When he heard of the portal he honestly tried his best to stay level headed, but living on top of a mountain your whole life tends to put your head in the clouds. Before long he couldn't help it anymore and he started to put one foot in front of the other.
With one foot in front of the other he walked off that mountain and into his destiny, whatever that happened to be. With him he only carried a few meager possessions (if you could call his massive Warpick meager) and the primal magics he had spent his whole life learning.
Taking one last breath of the cool mountain air his fiery red beard rose to attention, channeling the static electricity Thurdan couldn't help but make whenever he got excited. Finally, an adventure.
