Aaron appeared in a grassy field as he exited the portal from the tunnel. There were endless grasslands, and even a river running through the lands. There are trees in the picture, here and there, providing shade everywhere they are present.
He could even hear the chirping from the birds that were lying on the tree branches. He can see butterflies flying everywhere, making the scenery look like a paradise.
"Wow", he gasped in surprise when he saw the scenery.
Surprise and shock in awe would be the only reactions of anyone who appears in a paradise like that.
Aaron quickly pulled himself together and summoned his undead. One thing that he learned, or was taught in the academy, was that you never underestimate anyone or any situation you are in.
