As a Dwarf of King Dains people, Bregir travelled with the Dwarven army from the Iron Hills to aid Thorin Oakenshield in Erebor. His tasks were those of a runner or courier, and as such he took part in 'The Battle of the Five Armies', conveying messages up and down the lines as he had done in many skirmishes in the east. It is possible that he earned his name here, but it is not a story he often shares.

As the new kingdom settled, Bregir settled with it. Yet being stationary was a shortlived state for the energetic dwarf, and soon he was reassigned from his military duties to the diplomatic service of the new realm. His superiors found that Bregir had skills somewhat rare for a dwarf. His time as a runner had taught him the necessity of conveying messages clearly and precisely, and it soon became clear he had special talents in this field. Furthermore, he quickly became known as an exquisite judge of character, his warm and friendly eyes seeing through many a facade.

Through years of travelling in service of his king and through his keen interest in linguistics, he learned several tongues, although not always entirely fluent.  He quickly rose through the ranks and started carrying messages of greater and greater significance, ultimately with a great discretion in many negotiations.

Today he travels the lands of Middle Earth wide and far in service of his King and Country and will often be seen on his way somewhere with a leather-bound set of despatches. He is kept busy by many communications needing a curier and a diplomatic mind on their way between the settlements of Eriador, yet from time to time, he is at leisure and will spend his time in an inn or any other place that will offer hospitality.
