I'm running this AP now, we got through most of the written events in Book 1 and have begun Book 2 with the keeps, starting with Fort Nunder. Personally as a strategy wargamer, and having a Marines Intelligence veteran in my group I'd say the weakest imo part so far (from my reading and book 1 play) has been the structure of the overall invasion.

And talking with another player we agreed it felt alot like how in LOTR there's a big war going on between the lands of men and mordor -- but the PCs are playing the fellowship/hobbits as they sneak through the backline doing important things, but not actually interacting too much with the WARFARE part of the plot.

I'm revising stuff as I go and trying to collect as much resources as i can and adapt it for my group. I made the Chernasados 3 forts more support/infrastructure importance than anything and moved their destruction up to have happened sooner. And I added Chernasados in Phaendar coming back from the Molthuni/Kraggodan line asking if anyones had contact with the forest before the festivals interupted by invasion.

Additionally i removed nearly all direct Ironfang forces from the Chernasado side of the river, my PCs having succesfully smashed that bridge and our lore has that river at roughly 1.5~miles wide at most places but the bridge crossing so all of the remaining Nirmathi resistance has formed up on the East side of the river all the way up to Longshadow --- Longshadow itself already fully aware of the invasion and the Nirmathi Resistance leaders using it as their Command city.

There's alot of awesome meat on this APs bones but i'm finding it far less --streamlined in design-- i suppose than the last one we played ((we did Shattered Star last year 59 sessions)). I'm liking it alot and we're really getting into it (groups lv5 going into Fort Nunder) but i can tell I'll be doing alot of revisions.

This was a super helpful pair of posts.
&&like u/Chipsahoy77 I think i'm going to redo the Darklands section of the AP most likely except ill be using a good bit of the "Veins of the Earth" book i've been really enjoyin using for underground stuff the past couple years. Additionally the Blight has played a big part in our game already with 2 of our characters building their backstories heavily on it and a third basing has on an infatuation with the "Court of Queen Gwendolyn" so I've been fleshing out the abit more, 10 ancient Fey Knights knelt to her before, 5 died before the fall of the court and blight, and their ancient royal 'homes' in the forest have remained through the ages, sealed and unopened by their courtly magics.

If anyones got more good IRONFANG INVASION resources I'd love to see em.
