The Sword of Logos are a guild of swordsmen charged with defending the Wonder Ride Books and the main protagonists of Kamen Rider Saber.
The Sword of Logos was originally founded by a mysterious figure known as "Master Logos". Long ago, Master Logos was one of five followers of a mysterious woman who held the power to connect Earth with the Wonder World. Three of the woman's followers would become corrupted upon witnessing the power of the Book of All, becoming the Megid and attempting to steal the book. Master Logos thus founded the Sword of Logos for the purpose of defending the pages of the Book of All from the Megid and other malevolent actors who might also try to steal them. Using pages from the book, called Wonder Ride Books, the followers of Master Logos gained the ability to become Kamen Riders by inserting them into their sacred swords, with the organization's original associate Tassel is the inventor of the Kamen Rider Calibur equipments.
The New Buster
2 decades before the betrayal of Hayato Fukamiya (the current Kamen Rider Calibur), a veteran elderly Toshizaku Kamikawa (the original Kamen Rider Buster) is looking for an apprentice to succeed him while retiring as a teacher. He eventually choose a young Ryo Ogami as his student and eventually his successor, allowing Kamikawa to retire from his duty as a swordsman.
15 years before Touma Kamiyama became the second Saber, the guild was rocked when one of their swordsmen, Hayato betrayed them. Hayato attempted to sacrifice Luna, a girl who held the power to connect the Wonder World with our own, but was thwarted by the current Saber, Daichi Kamijou, though Luna was still sucked inside the Wonder World and lost. The guild believed that, after the incident, Calibur had murdered Daichi and sided with the Megid, when in fact Daichi had actually killed Calibur and taken up his identity to identify a traitor within the Sword of Logos who he believed was responsible for corrupting him, later revealed to be the current Master Logos, Isaac. The Brave Dragon Wonder Ride Book was also lost during the incident, though it found its way into the hands of a young Touma Kamiyama. Unbeknownst to everyone, Hayato experienced near-death and being saved by Tassel.

After the Megid attacked his town, Touma became the new Kamen Rider Saber and joined the Sword of Logos to assist in fighting them.
