Hoping someone from Riot can answer my weird question about details on the new Summoners Rift map

Hi. Sorry to whoever gets to deal with my ramble. I'm just curious about something. On the new Summoners Rift, the purple side fountain has symbols on it. Well, the purple side has them in general. Just curious to know if they stand for anything, or have a special meaning? I'm in the process of planning a tattoo sleeve dedicated to video games. I probably play League more than any game I have, so certain things from the game are going to be incorporated. As for the symbols and such on the purple side, I was thinking of either changing up the design of the fountain to cover my shoulder, or figure something else out. That's why I'm curious to know if the symbols mean anything. Thanks for reading :)
