I have sunk more hours into this game over the past week than I should have, but right now I'm stuck and don't know how to progress. I'll try to make this as detailed and non-spoilery as possible. 

I'm on chapter 3 at the moment and when I ask for quest advice all that Damia says is: "I sense a powerful magic presence to the west of the Royal City, deep within the forest. We should check it out."

There's a forest to the west of the Royal City, the one with the bee hive and the Druid temple, but when I go there i find nothing. I've searched a couple other forests and found nothing. The closest thing I found was in the forest with the fairy village where there appears to be a door that leads to some old temple, but when you try to interact with it nothing happens.

I think I have done everything else. I have gotten all the crystals in the area, defeated the boss in the sewer, saved the princess, impregnated the princess, and got all the girls into the mansion. But I don't know where to go from here. 

Any help is appreciated.

So after looking into this further, I think this is where the current build ends. I've searched the ends of the earth to find nothing, and I even looked into the Dev room to find no access to chapter 4. 

Guess there's nothing I can do until the next build is released. It's been fun though.
