A furious Erlys has demanded that you help her free Cariad.
'No one captures a member of the Cuan-lûth and lives to tell the tale. I'll tear apart Tornhad myself to release Cariad. You're coming with me -- Igrain, too. It's time to test you both and see where your alliances truly lie.'
Erlys has decided to free Cariad from Tornhad with your aid and Igrain's.
You should talk to her in the Cuan-lûth Refuge when you're ready.
