Ender-friend (end mob)

Ender-friend A neutral / friendly mob that trades only in the outer end islands. They provide maps to end cities, accept dragon heads for rarer items like diamonds, multiple enchanted books, etc. They could also be paid to teleport you back to the main end island. This mob is supposed to make venturing in the post-end game more fun, accessible, and less grind-y while not jeopardizing the core experience of venturing the end.
