Can anyone tell us what those horned skulls mean next to the name of the guild at the top of the table? And above all: why the guilds in the first places have barely finished the first worlds or the second ones while the others below them are already at the last boss of the last world, shouldn't the latter be there in the first places? Sorry for our ignorance about it but we don't really understand this thing! Someone has the kindness to explain to us how things stand. Thank you.
