You must have been in the jungle for too long. Your friend is being tortured by fiendish thoughts.

Did she say anything about a headache? The likely cause of these terrible thoughts is a nightmare. Even if she hasn't mentioned anything of the sort.

She needs the wisdom of Arbolu, the Ancestor of the Elim, to banish these thoughts. But not just anyone can speak to Arbolu.

Meet with Idarus. If you help him, he'll tell you how you can reach Arbolu.
Arbolu is the... ancestor of.. the Elim.

Not just anyone... can speak to him, Daeva...

But I will... tell you... if you help me.
