Since this is only 1 mod I just put the download for the Forge download. not the entire folder.
In Error says "The game crashed due to an unexpected error, error code 1." And by Abelisk I meant Waystone, located in villages, allowing teleportation between them. Maybe the whole problem is that there were more than 8 thousand blocks between the place from which I wanted to teleport and the place where I wanted to teleport?
