Mystcraft Reborn

Players build dimensions by collecting biomes into a notebook, then finalizing the selection at a writing desk, which turns it into a descriptive book. A notebook holds up to 16 biomes, and individual biomes can be removed from the transfer queue before the book is finished. Dimensions written this way can be explored, and a rewinding book opens portals that carry travelers in both directions.

The mod is a later take on the classic Mystcraft design, with mechanics drawn from Myst from 1993. Portals are built from a nether-portal-style frame of crystal blocks in a chosen color, with a book receptacle occupying one spot in the bottom row, facing outward and upward. A camera prints pictures and videos into picture books, and it doubles as a telescope by zooming out. The content suits survival-friendly modpacks. It runs on client and server, and is published for NeoForge 1.21.1 under the Creative Commons Attribution Share Alike 4.0 license, which does not make it open source.
