As per the comment before me. And yes, there's no trace quest because PA. Just autopath to the node manager and follow the fiery hoof marks once you're there.

Thanks guys in comments, it helped me a lot.

After finishing the quest Secrua, the Daughter of the Sun, a route is set to Gavina Great Crater. Once you arrive there, you see a fire path appear, check the screenshot. There you can see how those flames look on the ground. Check your settings if you don't see the fire path. This path leads you towards the npc and you can pick up the next quest.
