Forum:Olra does not appear ??

Hello. I am playing DD dark arisen and have just defeated the dragon to enter "post dragon" stage of the game.

I thought my strength / experience now adequate to  tackle bitterblack isle but I have visited the peir at night numerous times and she is never there. Obviously I am frustrated as unable to play a big chunk of the game and receive the benefits from doing so. I would be very grateful for any help / advise regarding the reason for this and how to solve it. Thanks in advance.
