Maiden, Mother, Crone - Witch Tree Riddle

[JackNapier89]

Hi guys i have a question... maybe a stupid question. I am italian and i'm playing the adventure path in the original language. I can't understand the meaning of a verse of the riddle of the witch tree guarding the enter to Artrosa.

He befell the wrath
Of two times seven

I understand the literal sense of the verse, but i don't undertand what it refers. What it is "two times seven"? Is a reference to quest past events that do not I take?

Thank you

I think that it's a reference to Elvanna, 14th (two times seven) queen of Irrisen.
