Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Black Cove - room with storm cloud

Hello,
in the room to the right of the one with Belegar I managed somehow to create a storm cloud in the lower left corner.
I do not remember how I did that (maybe a trap).

Is there a way to "remove it" ?
There is a drawer I can(t reach because of it.

Thanks,
Imarion
