I purposely stayed away from mountains this game. Last game I was on a mountain and in the mountain, so decided to go a different aroundt his time just by building on flat grass.
And if anyone still needs an enchanting table just use /warp fuzzy and mine is located in the house.
I aaaalmost died by falling into a giant cave while exploring the surface. Had half a heart left. Was a long ways down. The cave had a one block opening, and I didn't see it.
Also found a very large... crack... in the jungle. It had mineshaft railways running across the middle and connecting both sides. Was pretty cool.
