Note that the following contains a huge spoiler for /Sethra Lavode/. Indeed, it builds on the pararectal idea first expanded upon in the post archived here (which also contains spoilers, obviously): http://dragaera.info/mailinglists/archive.cgi?1:mss:14154 So it might be pararectal *squared* (pararectangular?). In /Taltos/, before Morrolan & Vlad actually make their descent over the Falls and into the Paths, Morrolan becomes distracted by the statue of a dzur, obviously representing House Dzur. When Vlad comes over to wonder why Morrolan is so fascinated by it, Morrolan explains that it is where those members of House Dzur are put in the River to go over the Falls. Vlad, still not getting why this holds so much interest for Morrolan, asks if he knows anyone who came this way. Morrolan replies "Sethra", and refuses to elaborate when Vlad says, somewhat confused, that he thought she was a Dragon. Up until now, speculation about this scene has tended to revolve around (a) the possibility that Sethra is of mixed Houses, but that since she's Sethra, and indeed *predates* the Houses, no-one makes an issue of it, or (b) Sethra was made an honorary Dzur by House Dzur by virtue of having defeated 17, and probably far more than 17, Dzur Heroes, and when she was killed the first time (before coming back as undead), she was honored as a Dzur Hero might well be (perhaps by the Dzur who killed her? Who can say?). Yet one has to wonder: Would Sethra have divulged the events surrounding her death to anyone? She is, after all, a very private individual, and does not seem to be disposed to confiding deeply private matters even to her friends. Of course, it is possible that Morrolan learned of Sethra's death from someone else. His refusal to elaborate might suggest that he realized that he had been slightly indiscreet and that Sethra would probably prefer that such matters not be discussed. However, I was thinking about that scene in the context of my earlier idea, namely, that Morrolan bears Tazendra's staff, and has access to Tazendra's memories. So what he might have been about to say was "Sethra had a friend and student named Tazendra Lavode, who was given to the Falls here", but then realized that this was a matter that *he* did not want to discuss at all with this Easterner and Jhereg that he only barely knew, and cut himself off, and stopped talking about it. Vlad, of course, would have no idea as to this backstory.
