Just doing several reintepretations of default skins from Minecraft, here is the last part with Efe. They are a 30-year-old resident of the Minecraftia City who goes out on adventures, practices alchemy and magic (to an extent) similar to Alex, and a friend and mentor of Sunny. Efe is known to be persistent, loyal, hardworking, patient, and cautious. They had gone to the End shortly after the Ender Dragon's defeat and had raided a few End Cities.

(There's technically 2 more default skins in the game but considering that in my lore Miriam and Percy are considered to be defaults. Besides, Minecraft Story Mode for example did not have Steve and Alex in it, so why should I have to include all defaults?)
