Idk if someone already asked this, I saw some posts on how this fit is pirate-y and probably goes with Pirate Caleb myth theory, apart from that do you guys think this could be MCs dress in Sylus birthday card, Yes I'm basing this all on the fact that we got MCs dress during previous to previous banner of Rafayel's birthday banner😂, I'm asking because it's so fun to predict stuff (and be wrong lmao) and I've been looking forward to Sylus's birthday so muchhh to a point im restless, you guys tell your overall card theme predictions as well and come back to this post to see what was all right or way far from our predictions
