Sir Nigel Goodberry is a dwarven druid who resides in the Greenhaunt in northern Breland. He is part of a circle of druids that live in the forest and create Goodberry Wine. They are the only group on Eberron that know the secret fermenting technique to preserve the goodberries.
If asked who knighted him, he responds that he was knighted by the squirrels of the wood, and he takes his responsibility very seriously.
