Another well-written chapter 🙂 . Katerei seems to have something of a penchant for somewhat self-destructive behaviors (i.e. her homeless lifestyle in this case).
I'm curious about Suriel's plans & how Tiernan plays into them. I never really understood that in DM/OoR.
If memory serves, alt-Selax learned that alt-Avatara had knowledge (or an ability) that he believed might be useful to him in his quest to reach Cythera. I don't think that it was ever specified what exactly this was, and, due to Selax's interference, alt-Selax never ended up actually needing it.
