Rise of the Blades
Kalashtar, which in Quori means “wandering dreams,” first came to Eberron 1,800 years ago. They came as a renegade group of quori spirits from Dal Quor, the plane of dreams. Agents of the evil quori known as the Dreaming Dark hunted them until finally the group of refugees leader, Taratai, found an audacious way to escape the clutches of the Dreaming Dark. She convinced Sarlonan human monks to to accept a permanent fusion of their own souls with those of the renegade quori. From that synthesis came the first kalashtar, and as a result, kalashtar today look similar to the monks who served as the first willing vessels.
The monastery where the sixty-seven humans became kalashtar was a place of refuge, so the humans who lived there wer diverse. Kalashtar have such retained a diversity of appearance, possessing the same variety of skin, hair, and eye colors found amoung humans. They are usually slimmer and taller than humans, though short or stocky kalashtar exist.
Kalashtar physically develop at the same rate as humans do and have similar life spans. A kalashtar child passes for human at first glance, but a few minutes of observation reveals the key difference. All kalashtar have a manner that is graceful, serene, and serious because of the fragment of quori soul bound within them. While human children run, laugh, and play, kalashtar children engage in the same meditative exersices, martial training, and telepathic coversations as adult kalashtar. For a kalashtar, growing up is purely a physical process, not a mental or emotional one.
Most kalashtar remain in the temple-keeps of Adar, so any kalashtar traveling around Khorvaire probably has a good reason for doing so. A kalashtar might be driven by a desire to break the Riedran siege of Adar, or could be on the run from the Dreaming Dark. The typical kalashtar is contemplative and serene. They are compassionate and friendly, but in a cerebral way. Perhaps due to the turmoil within their conjoined souls, kalashtar keep a tight rein on their emotions. A kalashtar demonstrates camaraderie with a wry grin and an offhand remark rather than with a backslap or a ribald joke. The fragment of quori soul in a kalashtar recalls the escape from Dal Quor.
Kalashtar on the run from the Dreaming Dark are wary, although they still try to maintain polite and kind behavior. Kalashtar struggle to integrate the thoughts and sensibilities of their human halves with the strange, intangible memories of their quori souls.
Kalashtar flirt with madness. Occasionally, a kalashtar’s serene countenance drops to reveal crazed and baffling behavior that is inappropriate or even dangerous.
