When Merge was born the family wasn't suprised at how big he was, his mothers bulge was extraordinary when she was pregnant. She wasn't expected to survive birthing him but through spending a goodly sum of the family funds to hire a Cleric to assist in the birth she managed if only barely.
Once born Merge's Father gave him his name as a loving slight against the child (I tried to think of good word for big & white in Dwarven), For he Truly was large and pale. Due to his odd skin color and unusual size the other children came to call him Meine-Durgel (little Giant). The teasing didn't bother him, he knew what he was.
When he turned 122 he decided that he wanted to spend more time with himself. So he packed up his stuff and headed out to find his place in to world. He found that nature was the perfect place for him to be when he wanted peaceful, quite contemplation.
But now merge feels the dwarven call to battle in his blood... Or maybe its the giant part? Either way he wishes to join an adventuring company after his hundred years of relaxing in the forest.
