Once you are able to unlock Ashaya, if you go through the frozen ice burrow there should be a wolf/dog there and if you're a high enough level she'll give you a quest about making a path through the snow/wall and after that you'll get to the cave to midnight mountain and again, if you're a high enough level there'll be a questline from the exile guard that ends up with you talking to a zombie dog, Lenore, then you will have to fight off some monsters while Lenore tries to throw you to the entrance of MM
