(I made it so fast I didn't even expected, I thought it will much longer and harder
So, I decided to turn this into a story in pictures, though I don't know how many parts there will be.
And background is strange for me, there's not so many things but it looks kinda finished. Anyway, I'll think of something.
Even creepy creatures as Slendercolt (that's my choice of transformation of his name, before you start asking) have their own fears and his - strange black-coat mare he met not so long before. Endermare suggest him a block but he refused it and ran away into the first cave which was marked by the light of torch. But I think it won't help him for so long.
Next part: somewhen later.
