The Lyre is one of the higher ranking members of the Order of the Ancients in Assassin’s Creed Valhalla.
Your objective is to find and assassinate The Lyre aka Tatfrid who is hiding in Grantebridge.
Here’s how you can find The Lyre (location) in AC Valhalla.
Location of The Lyre
You will unlock Tatfrid’s location after you kill all of the members under his branch.
He is in the marketplace or playing music on stage in Grantebridge, Grantebridgescire.
I found him at the exact location shown below, marked by the player location.
He was just sitting on the bench outside the convenience store. Assassinate him to end his reign.
