Hey Ahuss, welcome to the forums 
Don’t worry about posts going missing, I think it’s the first 5-10 posts we moderators have to ‘approve’ so they’ll be around somewhere. I just did this one to get you started.
Can’t help that much with the landscape side of things I’m afraid… did you start in a completely blank environment with nothing in the Scene Outliner? If so, try adding a directional light to the level. You might have the viewport in ‘lit’ mode and therefore all you’ll see if you have no lights is the void… you could also change the viewport settings to ‘unlit’ mode (top left of the viewport)
