[Java 1.16-pre5] Quick Nether access, portal&village close to spawn with 2 blacksmiths

Probably there are maps with a closer portal, but this one is at +270 +310, has only one block missing and no crying obsidian, and the chest contains obsidian and flint and steel.

If you want to gear up, the 2 blacksmiths in the village between them hold a full set of iron armor. The village has a few more chests to raid (loot partially visible in the screenshot). You spawn in the nether in a small opening to a larger area, it's fairly safe. Nearest nether fortress is directly south of the portal, you'll need to dig though
