Kalashtar were originally formed when 67 adaran monks fused their being with quori spirits from Dal Quor. All descriptions of the race, as well as their naming convention suggests a 1:1 ratio of human:quori, ie. that in one kalashtar there is exactly one quori and one human.
Combining these two statements could lead one to believe that the number of kalashtar is limited by the number of quori that escaped Dal Quor at that time. Is this so? I see no mention of such a cap.
If there can be more than 67 kalashtar at a time, where do the quori come from? Do they also reproduce? Do new ones escape Dal Quor?
Best Answer
Yes, there are more than sixty-seven kalashtar. There are also more than sixty-six, since the kalashtar bound to their leader, Taratai, sacrificed themselves to produce the shroud resonators that protect Adar (Secrets of Sarlona, pg. 24).

Here we see numerous references to kalashtar giving birth to kalashtar bound to the same quori spirit, references to “all of” the kalashtar bound to a given spirit, “Two Vakri kalashtar,” and so on. Nothing seems to come out and say it, but none of this would make sense if kalashtar could only exist in one-to-one relationships with quori.
