Anyone else read Steven Brust?

If so, I’ve been annoyed by something I can’t figure out.

To wit: who the hell is the Warlord during the Vlad books?

At the end of Sethra Lavode, Sethra Lavode resigns as Warlord and is replaced by Sethra the Younger. The next book in the timeline is Jhereg, and that plot revolves around who is going to be Warlord when the Dragon Emperor takes the throne, and as much time as Sethra is spending at Castle Black, I don’t think she could still be warlord. Then at the end of Jhereg The House of Dragon decrees that Sethra the Younger can never be Emperor or Warlord, but doesn’t mention her having to step down.

So who replaced Sethra the Younger as Warlord between Sethra Lavode and Jhereg?

I’d also ask why, except that I think the answer is pretty self-evident.

And yes, I know, that’s a pretty ridiculous question to be asking, all things considered. Except that I really don’t want to do my Survey Methods homework, and pondering Dragaera is nice distraction.
