Robots: They returned home from the mission, but when they were above elvenars, their spaceship broke down and fell on the mountain in the elvenar. That's why they asked for assistance from elvenar residents to repair their spaceship to return home, and in return will give them their best technology.
Demons: Their planet dies and their master Nephritis sent his best scouts in search of eternal flames, so they came to the elvenar in search of information that the elvenars had about eternal flames and offered their knowledge of better and quick production in exchange for information.
Angels: The Supreme Master learned that the elvenar had visited the demons, knowing that they were corrupt and greedy and that they did not keep their word, and therefore sent their priests to cleanse the earth from evil(without killing the inhabitants) and that they needed a new source of magic which they need to fight the demon. The magic that the elvenar has in huge quantities and that the inhabitants allow them to build the temple as a source of magic, and in return, send the best warriors to train elvenar warriors and give them some of their very valuable artifacts.
