for a long time, i considered myself to be a knight of light. this is because i got light as my aspect on the extended zodiac quiz multiple times and the knight class just seemed to fit with it for me, considering how important it is to me that myself and others know the correct information about things
however, i recently retook the extended zodiac quiz and got hope. this kinda bothered me at first, because i don't like change, even when it comes to something that is unimportant in the grand scheme of things, like what i get on a homestuck quiz. but after thinking about it for a bit, i realized it fits me even better than light! i am generally a chipper person, and i really want the world to be a better place someday. i hope strongly that things will improve for people when i see them down on their luck, and often do things to help the people who are (such as buying things for the homeless or trying unreasonably hard to cheer up an unhappy friend)
as for class, i still view myself as a knight. this is because i try quite hard to keep myself and others optimistic and happy, thus "defending hope". i think knight of hope is a pretty cool classpect, and i'm pretty happy that it's mine :)
