What if Minecraft had a new legand. This legand might form with a temple, or a mob. This legand starts with a village. I. wanted to add a legand because if we had legandary temples or mobs, Minecraft would have more objectives to clear. I thought that because alot of my friends quit minecraft because "no reason or objective to clear" they said that. I felt sad day. so I want a mew minecraft with more legand and mobs. If something like this comes out, ill feel curious how the temple looks. Berfore it, Notch added the strongholds. these are simaller but no unique mobs protecting but silver fish. But in a temple I think, I want to add stronger mobs like, half zombie creeper. I want to make it by making a mod. But sadly I dont have programming knowledge. If i had it, I would allready made it. I wish this sould have helped. thank you
