Thanks Ian, it is good to know there are no clashes and that it fits well with the theme of vol 5. Looking forward to reading it when it comes out.
I agree that the end of the adventure does get beyond the level of starting characters, but I feel a lot of rewriting would be needed for experienced characters.
Trying to avoid spoilers - as I see it the start of episode 1 can end up being a "James Wallis Ruined my Characters Life" moment for experienced characters as they get railroaded into losing some/most of their possessions, then Corflu in episode 2 as written seems pre-Lunar invasion of Karse (1619). Potential fights up to the end of encounter 5 in episode 3 seem geared to lower level characters. While encounter 6 in episode 3 is truly epic, the characters have the option of sitting back and letting others do the heavy lifting (based on the characters planning).
Overall episodes 1 to 3 seem to me to be geared more towards lower level characters and giving characters/players new to the area a good sense of the land and a connection to Zola Fel as an alternative to Pavis. It also possibly gives the characters knowledge about what the Lunars are doing in Corflu in time for somebody to do something to stop/delay the invasion fleet or to intervene in the recovery of the Watchdog.
Then in episode 5 it seems to switch gear, the Eye of Wakboth comes into play and the training wheels come off in a major way.
So upgrade/rewrite the start or downgrade/rewrite the end or perhaps the adventure is best split into two parts. Up to half way through episode 4 in 1618 or 1619 with less experienced characters and then delay the divination that the problem is not solved for at least a year (the reason for doing it immediately is weak). Have them be (minor) celebrities in 1618/19 and then hit the characters with "you said you had sorted this out" (with all the political fallout of that) and have them tackle the real source in 1620/21, by which point they may be tough enough to survive.
The big questions are: does that equally fit with what is coming in vol 5 and will the POD of vol 2 be out in time to put it on my Christmas list?
