First off, allow me to say how good this little quest is, well written and fits (for me) into BG perfectly. It has the right "feel" to it (unlike anything Neera utters for instance).
First time I found her, didn't even realise it was the mod, thought it was something I'd somehow missed over the years.
Plus the boomarang dagger is so good for Edwin, in particular, I spent ages looking for it in BG2 last playthrough, no such luck though.
Any chance it could be extended into BG2 and you meet her again in the Sauhagin city?
Ultimately of course I'd like to reunite her with Keth'Sim (perhaps in Sudanesselar?).
Would even like her as a joinable NPC, an evil assasin??
