I don't know which novel or movie 'The Great Magician' refers to, so it doesn't provide a relevant feeling. If you can provide more information or context, I will try my best to answer your questions.
I don't think so. Usually, we have common genres such as mystery, romance, science fiction, etc. 'great mage 4000 novel' doesn't seem to fit into the typical genre categories that are widely recognized. It could be a very specific or even made - up term for a particular work rather than a genre.
Sadly, I can't provide the name of the author of 'Great Mage Returns Novel'. Maybe you can try looking it up in a specialized novel database or asking in a relevant reading community where people might be more aware of this particular novel.
I'm not sure exactly as I haven't read it. But generally, it might be about a great mage who comes back from some sort of absence, perhaps from a long journey, exile or even being thought dead. It could involve his adventures as he readjusts to the world he left behind.
One of the main missions in the Greater World was to find the archmage. The Archmage's office was located in the upper right corner of the second floor of the castle. Players need to enter the right door of the King's Courtyard and then go up to the second floor to find the Archmage's office. In the office, players could find a divine artifact and a Lava Breathing Technique. In addition, there was a side quest to find the archmage's room and steal items. The specific location was on the top of the mountain on the right side of the map from the Imperial City. This place was called the Sky-gazing Horizon. In summary, players could use the above methods to find archmages in the Greater World.
I'm not sure specifically as there could be many different 'great mage light novels'. But often, there would be the great mage as the central character.
Typically, in these kinds of light novels, the mage's return often disrupts the existing power balance. There might be a young and inexperienced protagonist who has to quickly adapt to the new situation. The returning mage could bring back forgotten knowledge or magic that was lost. For example, they might introduce new spells or ways of combat that the current generation has never seen. There could also be a mystery surrounding their return, like a hidden purpose or a prophecy that led to their comeback.

It could involve magic battles, the mage's journey of self - discovery, and interactions with various other characters in that magical world.
