The sweet lilac behind the cold cyan

What if the corruption that invaded Nightmare's mind after eating the apples disappeared?
When he woke up after a long sleep Nightmare found himself in a place he didn't know. He couldn't sense his brother or mother anymore and was covered in some weird goo. The last thing he remembers was the fight he had with the villagers that wanted the apples.
Will he be able to go home back to his family? Does he even truly want it?
