Yasuo's brother or enemy in lore possibly hinted at in the Project page

Hi, if you check out the page or just this picture

Every node has a MEMORY TRACE_many digits, these digits are all different except for two champions: One is Yasuo and the other one is the "TRACE LOST" which hints at someone unknown or even dead. This could hint at someone related to Yasuo so either his brother who "died" in the lore or the one who killed his elder using "wind techniques".

Thougths?
