Dinnshenchas-Fairy defender for RPGs

Dinnshenchas

Originally cattle herders for the fairy courts the Dinnshenhas where also appointed by a kindly seelie fairy king as the guardians of women who have been greatly wronged or endangered.
Appearing as short rustic looking men wearing dirty flannel wool and leather suits they are sneaky little creatures, capable of hiding within the smallest shadows and stalking those who have wronged women for weeks at a time.
When not exacting revenge they sit in the highest mountains watching the magical cattle herds of the fairy lords. However they do this while hidden so all most well see are lone cattle, this way they can strike those who would steal from the shadows.
Natural poets they spend their time watching cattle breathing the mountain air and taking in the splendid views of the mountains. At times they may take a liking to those who are honest, who try to find the owners of the cattle or come to their defense, or who are also natural poets. Those who they like will receive aid, gifts, and the wonderful company of these fairies.

Using The Dinnshenchas in your Fantasy Role Playing Game.
It is all too rare that there are creatures like the Dinnshenchas in your Quests, a creature that is friendly, which helps defend the innocent. Why is it that demons and tyrents seem to have free reign in RPGs? I personally have found that having a conspericy of good creatures such as angles and fairies working with good mortals to counter act evil beings has helped to make the games all the more fun. The Dinnshenchas could be used in one of these or they could be working to build their own order to protect the innocent, or even the fairies cattle.
For lower level characters or those being introduced to the world of fairy it is advantagous to have them do something that well gain them allies and the good opinon of the fey, but won't make them lords right away, having them part of a society to protect cattle for the fey is one way to do this.
