Larian Studios Forums Divine Divinity (English) Help/Tips/Tricks Question about house with ghost near Barracks

I notice a locked house NE of the Barracks and SE of Commander Ralph's bldg.

Out of curiosity, I saved and broke in to find a ghost.

I have not explored the house in "reality" because I fear I might break a quest I will receive later.

So, will entering this house, dispatching its inhabitant(s), and looting break a quest?

Thanks!
