After wandering about for a week, they left Formhaol on the slopes of Slieve Felim and set out again, reaching Áth Cúile Feá /Áth Croí/Cúil Fheá Formáile that night, their fourth camp.

Áth Cúile Feá is on their route between Slieve Felim and Emly.
The army would probably have travelled from Cappamore to Pallasgreen, crossing the Dead River enroute. The land in this area is level and would have made easy walking after the Slieve Blooms and Slieve Felim. They may have spent the night on the banks of the Dead River, sending messengers to the residents at nearby Doon Fort, Dún Bleisce and the cliffs of Cahernahallia close by, to assure them they were were friendly visitors to the area.

The following morning they would have had a short journey from Pallasgreen to Emly, through the rich golden vale land with its very fertile soil and soft rolling hills, passing Chancellor's Land. This land is ancient farming land sacred to the Goddess Áine of Knockainy. She may be still stalking through the land, intent on doing mischief to those who do not honour her.

That night, Ceathach the Druid left the camp and met Dubhfhios Mac Dofhis. Dubhfhios told Ceathach that there would be slaughter because of their march into Munster, and that they will not get tribute from the Munstermen.

The meeting of the Druids was reported to Cormac. He decided not to kill him because when he had tried to kill the druids, his own men had suffered.
