I can't be the only one

alright I'm reading back through the novel and I'm back on chapter named colleagues when caera first comes meet back up with grey in the academy and in one of the parts its talks about the symbol that is engraved on her brothers dagger "three marks for time, space, and life and the hexagon as a symbol of connection". i was wondering if there is a drawing of it anywhere as i would like to see what people think it looks like.
