So what happens to the hero who fights his/her way into the House of the Dzur? Were the candidate not Houseless, would not the members of his/her former house be a tad unhappy? Probably not if the hero were a Teckla or a Jhereg since one can enter either of those houses without having a defined genome. However, wouldn't the House of the Dragon be unhappy if a member were talented enough to enter the Dzur, and did so? Can one be a member of more than one House at a time? How about genetic purity? One can only procreate with members of one's own House (at least without incurring certain consequences). Would the House of the Dzur truly be honored by adding the genes of a Teckla hero? There seems to be something here that is either incompletely thought out or far deeper than I am. What is the House of a Houseless person? What is his/her genotype? "Half-breeds" seem to be lower than outcasts, but allowing them to join one of the 17 defined Houses is asking for mongrelization of the entire House, a concept inconsistent with Dragaeran eugenics. In summary, I only see problems with two types of Hero who try to join the House of the Dzur: Those with a House and those without one. Among those with a House, little trouble would emerge for Teckla or Jhereg, but it seems unlikely that a member of one of those Houses would be welcomed with open arms into the Dzur.
