After taking a nap, I got a text from Albert to meet him before I check on the missing agent's condition. So I opened a portal to his location and hear what he's going to say.
"The agent is still alive at least. He contacted my phone and let it on so I could hear his conversation with other people there. But it was just for five minutes since someone suddenly come and he stopped the call," Albert said.
So that guy is still healthy enough to call Albert. But maybe the act of calling Albert made a reaction to a master level mage's magic detection and so he needed to stop it before they realized what happened.
"There was someone over there who was trying to heal him. So he talked to him while also talking to himself. He stopped the call when he heard that someone was coming so I don't know the full detail. But I will tell you what he said before the call ended," Albert said.
