Felipe? Must probablyHis friend is going to betray him, isn’t he?
As per the manga, Felipe doesn´t know that's Yona the one capable of reading ancient script, though he may suspect somethingNot sure if they told him about it, but it is certainly suspicious to try to leave behind the one who can read ancient script while following this clue about the ancient script.
That's what makes it look like a trap meant to attract people who came to the tower much later than the original occupants.I find it funny that the message says "heights of Ancient Magic." I mean, I get it. It's magic so old, the ancient wizard calls it ancient (instead of just calling it Magic in general).
