“Sammael has the person hide somewhere within Adytum during the day. If he can't find the student in an hour, then he lets the person join the next scavenger party.”— Lorraine
Sammael is a scavenger in Adytum in Fallout.
Sammael tells the Vault Dweller of a scavenger he sent to get the parts needed to fix the hydroponic farms, but the scavenger reported that he had found the parts and then never returned with them from the Deathclaw-infested warehouse in the Boneyard.
Sammael appears only in Fallout.
