You must complete her quest to find a cave before she will be at C-2. I'm not sure the gird# of where she is before then, but its not far off from one of the towns.

do u know where the cave is located?

The Ice Cave's. Its a blue haze on the map, not far from the portal.

The ice cave thing was for frost and not for tanya.
I need the one for tanya.
