Arcanic Scale (アルカイニックスケール Arukainikku Sukēru) is one of the most powerful Dark Guilds in Egalia and wish to overthrow the Ministry of Magic and take over Egalia, transforming it into a Dark Mage Continent (闇魔導士大陸 Yami Madōshi Tairiku). They do not have a ranking system but seem to rely on aliases to determine rank.
This Guild uses a "ranking system" based on epithets/nicknames relating to the major arcana. These can be due to either their appearance, abilities, personality or even role in the guild. The members of Arcanic Scale also carry a tarot card on their person, symbolising their epithet, this serves as a form of Organic Link Magic: with each member of the guild being defeated, their energy will be 'donated' to Strombola and upon defeat - the card will become blank.
