this was a mod that is an unofficial addon to ice and fire and would've updated the end making it more in twine with the ice and fie theme (go to files for da mod)
below will be ideas that where for the mod
-ender dragon remodel
-ender dragonsteel armor (added)
-ender dragonsteel weapons(only got to add one)
-new biome plus new creatures that would live in it
-ingot(added)
-ender dragon egg plus tameable
and yeah as you can see this project was over ambitious and had to much for one person that can only add armor and weapons in the images tab are some development images (keep in mind that some of the images in the well images tab are only concepts and wasn't the final product)
