One other reason to travel to the Nether, is for some of the resources
it contains. Such as mushrooms, which are quite rare in the other
world, but as common as trees in this dank realm.
The bricks and blocks that comprise the Nether can be easily harvested
and freely transported back to your home in Mineworld. One of the more
noteworthy of these bricks is the lightdust bricks that hang in
chandelier-like fashion from many ceilings and overhangs.
They break very easily and make a shattering noise like glass. When
broken, each brick yields one lightdust powder.
