Episode 17: Secrets and Lies is the first episode of the Hand of Henrin series.
Episode 44: Things to Come is the second episode of the Hand of Henrin series (and has also some particular interest for characters involved in the Saga of Hadeen... and in the underground fights against the Afridhi, by the way).
I actually took the liberty to adapt an adventure from another setting, Raiders of the Desecrated Temple (more detail about it here: https://fightingfantasy.fandom.com/wiki ... ted_Temple), and I run it before the other two (it worked perfectly).

Now I have an issue: I can't find the next adventure in the Hand of Henrin series. Maybe I missed it, maybe it is not clearly written in the introduction... how does this series continues / ends?

I do not think this was finished but I will hunt down some notes for you. I'd reach out to P.J. and Tim on the Facebook group too.

Thank you so much!
Some indication is anyway better than nothing!

Well... I guess that now anybody's guess could be a good guess...
Maybe you want to have a look at the end of Episode 44: Things to Come where there are quite strong links / seeds to a sequel and help me putting together a follow up adventure and, maybe, the end of the saga. 8)

Let me try raising this topic again: any suggestion for continuing this saga (based on old notes or on new conjectures) is welcome!

You'd have to ask Stewart Larsen I think. That wasn't one of the arcs I worked on.

But it sounds like silver dragons are involved...but they are Lawful Good so...maybe this guy is corrupting them somehow and needs the arrows for that? And with all the "experimenting" I wonder if this guy is also a follower of Hella, too?

I mean this one is a tough one without more context...but...maybe they are making some kind of undead silver dragon in the hills.
