Okay, I don't know if this was put in the game recently or not, but right after the fight with the adventurers, if you follow the dialogue tree with Zevlor he'll tell you about The Descent and Elturel basically casting out the tieflings of the city.
So the info about the reason for all the tieflings being here is available and it's in one of the most immediately obvious conversations. It's just a bit buried which is common for lore/backstory bits that are common-knowledge for existing fans of the setting.
