I noticed that the word "Abbasid" has appeared a few times in this game, as in, "Abbasid Ribs" and "Abbasidose." Kinda like how the names of characters and locations are used. So is Abbasid a location, or some mystical being?
The Giants do not have a clear enough mind-picture of it themselves, at this point. Keep building new streets and donating to shrines and stuff and I'm sure the Great Lost City of Abbasid will rise again!
