Peace with the Dwarfs - Where is Taron/Ardan's Peaks?

[Roman]

I have reached Kordar through the mines and have been sneaking through Upper Hadar to try to find the Dwarven capital Taron, which is supposed to be in Ardan's Peaks. The only further passage I found, however, is underground and leads to Lower Hadar... well, I doubt that "Peaks" will be located underground.

My mage is only level 12 - hence my sneaking around rather than fighting through the stacks, which would lead to heavy losses for me at this stage. I guess I should probably return to the Isles of Freedom to gain a bit more experience, but I wanted to complete this King's quest to unlock more infinite units and access to another continent, so that I can pick and chose where to go at what time.
