The quest is in Riven Spire in Traitor's Tor.
In the quest description in your journal, Victory is spelled "vistory".
From the quest journal
"Undead Soldiers have been Haunting Traitor's Tor ever since the end of Ranser's War, but no one's been able to find out why.
Within the vision of the past, the Orcs of Wrothgar have breached the walls, but King Ranser refuses to surrender. As a last ditch attempt at vistory, I'm to pour magical packets into the brazier in the four towers."
