Born to Wynnwold of Aldburg and Pelafir of Gondor Aerynnwold was a much younger child than her brother Pelaphor, who in Rohan was called Gedrec. She wass but a child when her father died in a hunting accident and her mother soon afterward. Her brother having left for Gondor by that time she was raised communally by the women of the village but often bullied for her mascluline build and plain looks. She developed a reputation for trouble and brawling among the other children and one day seriously injured a boy causing her to leave the village for a solitary life of farming at the age of thirteen. From that time on she lived fairly happily alone on a hillside not far from the village, often selling pipe-weed to a merchant in the village who would then take it on to Aldburg to the market there.

Recently she was forced to leave Rohan as her brother sent men to claim her land and seize her in order to marry her off to a Gondorian noble increasing his own status. She slew the men sent and was accused of Murder for it. She adopted her brothers old Rohirric name Gedrec and signed up as an Eastfold warden in the guise of a young boy, the position allowed her to move along the mountains and into Gondor where she sought word of her brother to find vengeance. in Minas Tirith she heard rumours from the house staff of Pelaphor's home there that he had left for the far north, Eriador as they called it. She begun the perilous journey north alone and still disguised as the boy Gedrec, taking the dangerous mountain roads she finally made it to Bree and came to contact the Eagle Guard.

At last she found her brother and after a brief conflict Pelaphor realised the error of his action and gave her full rights to the farm, however instead of returning home she chose to stay and help the Eagle Guard in defending the north land. She hopes to improve her relationship with her brother via showing her worth.
