I mentioned it in chat and liked the analogy so I decided to make this idea official in feedback cause really this whole tedium of "raise the knight to x level only for them to die and go even lower than it started" does feel like a punishment from the House of Hades.
Just like Sysiphus and his boulder we are given a task to raise our beloved knight to the highest peak, and some work hard, constantly hosting activities and tournaments and non stop battles and somehow manage to reach the top. Then you have some like me who can barely reach the halfway point by casually doing those things. Still the Gods care not which you are because your knight will die of old age and the glory will fall down back to square one. Just like the boulder, you need to keep doing it all over again. Those who work harder of course only fall to the midway point or something compared but still I imagine it gets pretty tedious after a while even for them. Especially since if you slip up and stop focusing all efforts on gaining glory then all the effort you've done in the past trying for your knight to be the very best was for naught.
