The Heart of the Storm

According to the documents you captured at Narvir's Cradle, the iron colossus is complete except for one key component -- the Heart of the Storm.$B$BWithout it, the iron colossus' weapons would be much weaker than the design predicts. If we can deny Overseer Narvir the heart, we could defeat the colossus!$B$BNotes on the documents you found say that the heart is in Uldis, a titan facility far to the south. Its entrance is on the south side of a tall mountain overlooking the Bor's Breath River.
