"So it's true, you're here for the blood..." With the Warding Feather in hand, you may now carry Meslamtaeda's blood. Meslamtaeda's blood is stored in the Purifying Altar inside the Contaminated Sanctum. You met a Notos legionnaire in the Contaminated Sanctum, who explained that the contamination was too severe to approach the altar safely as it was the exact location where Meslamtaeda's blood first spilled.
