There should be a Minecraft mod that lets you create portals to other locations in your world. For example, you could have one portal in your house, and another portal in like a village. You could just walk through the portal to get to the village and walk right back. It would be an easier method of transportation, plus it would look cool. There are already the nether portals and you can travel with those, but it just sounds like you’re better off without breaking your diamond pickaxe and not even getting all the necessary obsidian. Anyway, it should totally be a mod. It would be totally awesome.
