Destiny - Calcified Fragment: XXVI (26)

Calcified Fragment: XXVI found in Destiny The Taken King / TTK expansion. During "The Sunless Cell" strike, progress until you defeat the second part in the Asylum where you fight all the spawning mobs in the room with the large portal/throne seat. After you leave this room through the large doors, head immediately to your left and there will be a platform over the edge you can jump to on the side. The calcified fragment will be on this.
