Where is The Blazed?
Children of Danu
Is dropped by Cummascach
"Investigate the gravesite near the waterfall in Bally na Gall, a burned village along the Bann River in southeast Ulster."
There is a grave above Bally na Gall at the waterfall where you find Clue 2
"Investigate the burned houses between Black Pig's Dyke and Clogher in southern Ulster."
Between Clogher and the Legendary Animal Location is a settlement with burned houses.
That's where I found and defeated The Blaze. He did his rounds with his hound.
You can now find her at the Festival in Rathcroghan, Connacht.
When you have all the Clues, you can mark her as target in the Order menu.
