A monolithic grouping of several trillion Aslan,
the Syoisuis clan maintains its power through an array of vassal clans scattered
throughout the Hierate. Generally, the
Syoisuis avoid alliances, keeping their own interests in the foreground.
Some human observers perceive this clan as "dark and sinister,"
probably because of its restrictive and secretive nature. Syoisuis favors wars
of assassins, and has a mastery of intelligence and counterintelligence
unsurpassed by any other clan. However, its intelligence focuses on
reconnaissance and observation. The clan excludes such methods as extortion and
subterfuge - things distasteful to Aslan honor - but familiar to human covert
operations.
Neither does Syoisuis protect its secrets to give itself an advantage. The secrecy is instead meant to deny its opponents an advantage by denying them information, even things that by themselves seem of no consequence. Syoisuis does not depend on secrecy in strategic planning. Should its military secrets become known, its plans would change little. To do otherwise would be "sneaky" and not befitting Aslan honor.
