noone can you need to find it yourself. get the coords from the location database and go there "manually" *moved from general discussion*
If that's the case, then how are people supposed to know that location without the information being 'leaked' somehow from Troika? People hacking the game files? Some lucky bastard with too much time on his hands? *SPOILER* I'm surprised that certain followers don't tell you about it, seeing as they've fought wars and stuff in there.
Much information/history has been apparently lost in Arcanum, otherwise finding Tulla and Vendergroth would be a breeze. Another instance of lost history is the treatise regarding Dread Armor and the craftsmanship of the Iron Clan. The world at large believes Caladon to be isolated. We "rediscover" the old bridge linking North and South of the Western part of Arcanum and I would classify Gorgoth Pass as a rediscovery as well. As per how we may come to know these locations: sure, Troika can hint or even leak intel. Before becoming acquanted with tera-arcanum I ran grid search patterns while watching television, finding all mapsites not dependent on quests, timing, or dialogue.
I had looked for the pass the first time that I was playing the game, and even with the coordinates, never could find the darn thing. I am unsure what I was doing wrong. HUMMMMM!!!
