Introduction

Diallos is a pretty cool looking character when you first meet him, but then he just dies :(, It also connects with Tanithes questline.

The start of something

The questline starts of once you speak to him at the table of lost grace. He will tell you about Lanya and that she is missing. After that go to Liurnia of the Lakes (specifically near the Academy Gate Town site of grace) and you can see him mourning the death of Lanya. Talk to Diallos again then he will move the table of lost grace. After that talk to him again then he will move to Volcano Manor.

Once you get to Volcano Manor Diallos will be in the drawer room, Also in that room there is a seperate questline for Tanith

The middle of something

On the table next to Bernhal there is a letter that will give you the coordinates to the person that you have to assasinate. Every time you assasinate someone you should go back to Diallos and talk to him. After yopu finished Tanithes questline Diallos will leave among everyone else.

The End? (Already?)

You can find Diallos in Jarburg in one of the little shacks saying that he will forge his own path. After talking to him wait 4 in game days in Elden Ring, Then some Stupid ass fatherless retard kills everyone in the village, just why? Diallos will die from the events and you can see Jar Bairn will be standing next to his body saying that he wants to be a great warrior like Diallos. You can pick up the items diallos dropped.
