Where in God's green Kryta is the UW Forger?

There, uh, there is no UW forger.

Just to reinforce what Red Locust said, there is no UW armor crafter. I know reliable people who have cleared large amounts of the UW and never seen one. I have cleared around 80-90% of the quests myself and never saw it either. The people who DO claim it exists, always make up some BS story and obviously know little of the areas in the UnderWorld, they also can never back this up with screenshots. Remember how many FoW armor crafter screenshots appeared shortly after people started discovering it? Yeah, people like to brag when they find much sought after things like this, and the best way to brag would be to post a screenshot in a forum like this. Even ANet themselves have indicated that "Obsidian Armor" is the final "end game" armor you can obtain. In an update they made to their website they said something to this effect, referring to whats next after the major PvP update that took place:

"For those players who have finished all mission/quests and obtained their Obsidian Armor, don't worry, we have an update for you next"

And yes, they used the words "Obsidian Armor". What item is used to craft FoW armor? Obsidian Shards. Anyway, sorry for this rant, i just hate when people spread rumors like this with no evidence whatsoever, reminds me of the "Secret CoW Level" in DIablo I, which never actually existed... yeah, some of you remember that one.

Of course if someone can just post a screenshot of this UW crafter i will retract everything I've said.

theres a cow level in diablo 2 though

from what I understand there was a forger in UW in one of the betas but he is no longer in that spot.

Heard a rumor you have to clear all the momunments of grenth and do the quest to get it but havent seen any evidence

In Betas, the forger in UW was the same that now is in FoW
no evidence of a UW crafter now

LOL! I remember Diablo I and the secret cow level. Dopes would run up to the cows and say stuff like, "If it moos X number of times, a secret portal will open up." That it was included in D2 was a testament to the developers' senses of humor.
