(New type of villages) Villager camps with villagers (explorers)

It would be like a village, but much smaller and rare, and the houses would all be tentative with new types of villagers (explorers): miners, guards, mages and so on (You could buy items from everyone, but these villagers would be special because you could hire them with emeralds.) *Guard: While he is within a certain block radius of you, he will protect you in exchange for emeralds. *Miner: He would give you a list (of items within a radius of the camp) of mob or mineral items that, once selected, he would search for and bring back to you. within 1 day *Mage: This would be like a summoner, but would be able to summon special allies that would search for dropped items and their belongings after death within a radius of the camp.
