Fingon and Maedhros sketch

"There Maedhros in time was healed; for the fire of life was hot within him, and his strength was of the ancient
world, such as those possessed who were nurtured in Valinor. His body recovered from his torment and became hale,
but the shadow of his pain was in his heart; and he lived to wield his sword with left hand more deadly than his right
had been. By this deed Fingon won great renown, and all the Noldor praised him; and the hatred between the houses of
Fingolfin and Fëanor was assuaged."
