“Clock Tower”, the Highest Institute of Magic
The Clock Tower, the core of the Association and in fact what could also be said to be the Association itself, is based in the British museum of London. Magi from all over the world gather and devote themselves day and night to the study of magic, while at the same time, are busily tripping over and being tripped over by other factions and competing for power and budget. The organization is anything but harmonious and has a complicated bizarre structure, but the magical research there is without doubt the leading edge.

Below the building, there is the magi’s research area which includes studies and archives. It is only a venerable museum to normal people of course, but at the deepest part, there is a special area (prison?) called the “Bottom of the Bridge” where the Association confines many sealing designated magi deemed to be “dangerous because their talents were too outstanding.” Also, apparently the Gazamy the “Evil Spook”, treated as the number one disaster in the Association, is locked up at the bottom of the London tower.

The person of highest position in the Clock Tower, the “Director” has been the same person for the 2000 years since the founding of the organization, and because of this is thought to be something more than human.

The organization handling patents relating to magic is also the Clock Tower, and the current finances of the Tohsaka family is being by covered by the patent royalties that are being transferred to their account.

Ranks of Magi
A magus is given a “rank” that matches his ability. The highest is said to be Crown (Grand), but details on it are unknown. Note that Lord El-melloi II, lecturer at the Clock Tower who has produced many Grands among his pupils, is stuck in the mediocre “fourth rank” for some reason.

Color ranks
Separate from the normal ranks, color-based titles are given to those that have become special.
The highest are red, blue, and yellow based on the three primary colors. After that, there are the combined colors of orange, purple, green, black, and so on. The further down you go, the less your rank is. Note that there is no rule about only one person for each color. The Association will, without any stinginess, award a color to you if you’re a magus of great stature or one with an unusual talent.

Sealing Designation Enforcers
If you receive a “sealing designation”, you will be confined and even your magic research will be gone, not to mention your freedom. Thus, the person given that designation will of course desperately resist that and won’t stop fighting. To forcefully retrieve magi who were qualified enough to be given a sealing designation, the Association dispatches “Enforcers.” There are around 30 of them total, and Bazett is one of them.

Lords, consuming their time in power struggles
In the Magic Association, no rather, the Clock Tower, there are a number of families that hold sway. They are called Lords and are the objects of fear. There are three major families of Lords and about 20 families of relatives. These families are well-known even in normal society. The history of one family is at shortest 500 years and the longest is over 2000 years. They have been plotting and plotting since a staggeringly long past.

The Sea of Estray, together with the Atlas Institute, is an organization called the original form of the Magic Association.
Among the founders of the Magic Association, there had been many heretical magi who were exiled from the Sea of Estray and the Atlas Institute and had no place left to go.
The base of the Sea of Estray is in Northern Europe. This base, with the nickname of the Moving Stone Coffin, is itself a moving mountain range. Normally it is wandering at sea as its name suggests, but sometimes it comes up on dry land.
It seems they research mainly body alteration, but the specifics are unknown.

*What is an alchemist?
One who studies the flow of matter. That is what an alchemist is. The alchemists of the Clock Tower created products like the homunculi of the Einzbern by merging with western magery.
However, the ultimate goal of the alchemists of the Atlas Institute is set even closer to the original ideology, as the "transformation of events". The often spoke-up "transformation of base metal to gold" in alchemy is, to the members of the Atlas Institute, mere "transformation of matter" and is nothing more than a primitive art far removed from their ideals. Their alchemy is an advancement of the metallurgy of ancient Egypt, the root of the discipline, and has not been influenced by western magery like the alchemy that the Clock Tower magi handle.
