Petra holds out a case full of strange mementos. Despite their small size, their antiquity is apparent—as is the Taken corruption clinging to them. Petra starts to speak, and you hear righteous anger behind her clipped words.
"These are mementos of past Awoken Paladins. I don't know how the Fallen learned of them, but a Taken attack targeted the mementos… and desecrated them."
"Our honored dead deserve better. Take their mementos into the Shattered Throne and hunt down the Taken responsible. Their blood will avenge the wrong that's been done and purify the tokens."
Petra's frown deepens. "The Fallen hid themselves well. My scouts revealed some clues, but you will have to search carefully."
