Ser Eldric was the son of Ser Arnold Arryn, himself a first cousin of Jeyne Arryn, Lady of the Eyrie. Twice his father rose against her to contest her inheritance, claiming that women were too soft to rule. After his second rising, Arnold was imprisoned in the Eyrie's sky cells, where he went mad.
In 134 AC, Lady Jeyne died. In her last testament, she named her fourth cousin, Ser Joffrey Arryn as heir, though Arnold was much closer by blood. With Arnold still imprisoned, Eldric came forward to press his father's claim. Many lords supported his endeavor, insisting that the laws of inheritance could not be put aside by "the whim of a dying woman." Additionally, a third and more distant claimant came forward in the person of Isembard Arryn, the head of House Arryn of Gulltown.
Ser Corwyn Corbray, one of the regents of young King Aegon III Targaryen, ruled that Jeyne's will must prevail and declared Joffrey the rightful Lord of the Eyrie. However, when the claimants refused to accept his ruling, Corwyn ordered the imprisonment of Isembard and his sons and the execution of Eldric. Arnold was able to flee to Runestone.
