My internet history is surprisingly more tame than you'd think based on my h-scenes.
Ironswords: You need to reach the shrine of the wolf, northwest of Tolbana, but also NOT just beat the three ruffians to a pulp in the initial Mermaid's Song encounter.
Azar quest: Azar's missions aren't available until after Floor 4. I just copy-pasted the event from the previous version because I deleted Imperia Academia's old map and I didn't want to lose it.
Imperia Academia: Only the top building is available atm. Over time I will add more to it.
Sheep quest: On the road to the mountain part of Urbus from the "village" part of Urbus, turn left before reaching the fence. It's not a very visible path. It's after you climb the stairs.
