Children of Kalestraum
The Children of Kalestraum are a group of Moon Mages known for several acts of magical terrorism against the Moon Mage Guild and other organizations, as well as being the modern re-discoverers and developers of Teleologic sorcery.
History
When the Saesordian Cabal was founded in 718BL by Tezirah, they were the forerunners to the Progeny in the most literal sense, not only discussing the theories behind shadow magic, illusion, and sorcery, but the actual practice. Sorcery was a socially unacceptable and taboo practice but was legal until the Empire passed laws banning it 12 years after the group was founded. The banning of sorcery coincided with the order to execute Tezirah and the entire group went underground for three years.
When Tezirah was killed the group dissolved for nearly a century (79 years). Heronyous Kalestraum staged a reformation of the group at this time and it existed after this reformation as the Saesordian Cabal headed by Heronyous, including the Crowther family, for twelve years.
The stated reason in books for the Crowthers' split from the Cabal was that Kalestraum was more interested in the practice and development of sorcery rather than actual philosophical discussion and magic that was actually legal at the time (practicing sorcerers to my knowledge still being put to messy and painful deaths). What ulterior motives and desires for power on the part of the Crowthers is unknown, but the Crowthers split from the main group all the same, forming the Progeny of Tezirah.
Right after this schism happens and the Progeny forms, the Celestians begin to see Kalestraum and the Saesordians as a threat to their fledgling group and their desires for legitimacy in the Empire. The event we know as the Scouring takes place, lead by someone known only as the Eye. In plainer terms, the Compact went to war against the Cabal using unknown but apparently experimental group-based magic and won, slaughtering most of the group in the process. The remnants of the group, less Heronyous who was allegedly killed in the battle, go underground, not to resurface for centuries.
Current Events
The Children of Kalestraum is a hierarchy with the Shadebringer Karosti Kalestraum, descendant of Heronyous, at the top. Below him are three Scions: Ealuik, Everelles, and Xailes. Each Scion is assigned with a few Votaries that perform varied and sundry tasks for the group, several of which have been walked during the course of the event.
The Children are responsible for several major events and inventions:
- Destroying the Throne-Taisgath turtle
- Theft of a storybook from Tiv's guildhall
- Temporarily severing the Moon Mages' collective link to the Plane of Probability and disrupting their foresight
- Creation of the gaharzen device
- Summoning creatures from the Plane of Probability to attack students
- Murdering many people for various reasons
- The discovery and revival of Teleologic sorcery
Their more apparent goals seem to include developing their unique sorcery and destabilizing the Moon Mage guild. They have stated that they desire revenge against the leaders of the guild for past crimes, and the "students" (PCs) can choose to stay out of their way or die.
