Where to Find Albus
The first step in finding Albus is to head to the Albinaurics’ village, which is located on the southwestern coast of Liurnia of the Lakes. You will be able to recognise the entrance when the water transforms into a toxic swamp, and there will be a significant increase in the number of hostile Giant Crabs.
Continue forward through the town until you reach the Village of the Albinaurics Site of Grace. You should turn around and go back the way you came before continuing upward past the Crazed Perfumer until you reach a grave next to a large pot. This will allow you to avoid crossing the bridge that leads to the north. Roll into the pot or attack it to find out that Albus is hiding inside.
After you have a conversation with Albus, he will hand over one half of the Haligtree Secret Medallion to you (Right). After that, he will tell you to find Latenna, the woman with the albino appearance, and give the medallion to her.
You will find a surprise if you go back to The Roundtable Hold before you go looking for Latenna. However, this point marks the end of Albus’ participation in the overall quest. If you run out of things to say to him during this meeting, he will pass out right in front of you, and his body will vanish; if you run out of things to say to him, reloading the area will result in his disappearance, and it will be assumed that he has died.
