It's frustrating work trying to find mention of the temple in the library - the academic works there very rarely mention specific examples of temples complete with accurate information on their whereabouts, and when they do, few of the examples beneath Sharn seem to be in anything like the right area. Eventually, though, their persistence pays dividends as they come across scattered mentions of sacred Dhakaani remains in the right area which were built upon last century and now lie beneath an inn named the Slag Pit.
Upon meeting up with Baracus and Serris, it seems that their efforts at leaning on the locals in Khyber's Gate have turned up a good amount of corroborating evidence. Their enquiries were met at first with a good deal of hostility, particularly when the subject of the temple was broached, but between Serris's street smarts and Baracus's looming presence behind him, they eventually managed to gain a good amount of cooperation. Certain people recalled a fresh-faced group of adventurers who were asking around about a Dhakaani temple a little while back, and they were seen to spend a considerable amount of time in the Slag Pit.
Altogether, once the two groups have shared their findings, their course seems clear. A preliminary reconaissance of the Slag Pit's exterior shows it to be a dive bar of the worst sort. It is built into the cliff face of the natural cavern which bounds this part of the Cogs, and fronts onto one of the crude iron walkways which pass for streets here. A rickety wooden porch has been built over the entry way, and beneath it stand two guards, a bugbear and a hogboblin, eyeing the passers-by malevolently.
The rest of the street, such as it is, is occupied by lean-to shacks and shelters made of scrap metal, wood and filthy rags. The crowds around here are predominantly goblinoid, but with substantial minorities of humans, ogres, and other assorted races. Almost all of them look obviously pooor, and many of them seem to be sizing up the party's shiny equipment. Pickpockets are a constant hazard. The area is badly-lit, with most of the illumination coming in the form of a hellish red glow from the foundries, forges and lava pits that lie further below. The air is hot and close, filled with the heavy smells and overbearing racket of industry and mass poverty.
