Land of Sorrow (Shadow Dragon and the Blade of Light)

"Gra's betrayal of Altea years earlier had come as a shock, of course, until that day they attack Marth's kingdom in the name of Doluna, Gra had been a trustworthy neightbor and ally. While the Altean army was out on an expedition, Gra struck from the rearm annihilating the Altean soldiers, killing Marth's father, King Cornelius and stealing Falchion, the blade of light. It was a crushing blow.

''Much time had passed since that sad day, and much had changed. Now it was Marth's turn to descend on Gra Bastion, and face King Jiol, the man who had robbed him of his father."''
