RPG Module Review – The Secrets of Shirakawa Castle

A fantastic adventure, that pulls from a set of folklore and stories that really don’t get much chance to shine in tabletop RPGs.

This post will serve as part one of two of the Shirakawa Castle review. As such, its mostly spoiler free. While none of the plot beats are discussed, there may be some info about the types of Yokai encountered, the beings infesting said castle. Read at your own risk! So, lets get started shall we?

There are two big things about Shirakawa Castle that I think might turn people off, and that’s a real shame, because it’s a ton of fun. Graphically, the module doesn’t look amazing. There are no splash screens of amazing art, there are no bright colors. It looks like a word document. The second thing is the names. I’ll talk about this a bit more later, but I really wish a pronunciation guide/glossary was included. Tengu is easy enough to say. Osakabe-Hime, Yamatai, even the namesake of the castle, Shirakawa, not so much. One of the big pieces of feedback I during a post-game wrap up is that some of my players couldn’t remember who was who regarding the human family members.

So, now that we’ve gotten those small issues out of the way, how does the rest of the module play? Well, it’s a ton of fun! For starters, nothing in the module feels like a traditional monster. There’s no goblins or orcs. Instead, you get a menagerie of strange and bizarre creatures, including a giant foot that demands to be washed, a three tailed cat, kappas, and super small group of creatures called Yanari, tiny little men that like to cause havoc.

The module gives each of these their own statblock, attacks, descriptions, and even gives a bit of info about their behavior. To me, the Yokai are one of the strongest parts of the module, brimming with personality, and with interesting mechanics. The aforementioned Yanari for example, have the ability to swarm up a character and tie them to the ground. Each creature has something special about it, and also tends to have its own unique weakness, as you might expect from something of myth. In addition, most of the encounters can be handled non-violently, if you have players who would prefer to talk things out.

The module isn’t all combat encounters however. Players will most likely spend a decent portion of time exploring the titular castle, and interacting with it’s inhabitants. And this is where one of my second favorite things about this module comes in: The NPC Profiles.

Most of the time, when you get an NPC profile, you tend to get a few traits, or maybe a background. Shirakawa Castle does both of these, and then goes beyond, laying out for the DM the relationships each of the characters has with each other. Since a large portion of the module is investigation, this is a lifesaver when it comes to things like whose sleeping with who, or remembering grudges or problems. For me, this is one of the strongest parts of the module, since it prevents any sort of “Wait, but X said that Y is…” or stuff of that nature. For me, it made the NPC’s far more real then just being servants at the castle, or the lord, or the lady. And it made it much easier to roleplay them. It also prevents the problem of “Well, I thought they would encounter this NPC here, but instead X,Y,Z happened, what would they say?” Combined with the monsters, this is what really sells the module to me.

I’ll post part two of this review after we finish the module, but overall, my players had a ton of fun. While the module might look a little amateurish at a glance, the level of detail in the monsters and NPC’s mark it as anything but. It’s a fantastic adventure, that pulls from a set of folklore and stories that really don’t get much chance to shine in tabletop RPGs. That isn’t say it is perfect, but it’s weak points are only in presentation, and a few additional things that would be nice to have. If your players are board of facing the monsters of European myth, or you want a great mystery module with varied and interesting combat, I’d definitely recommend.

Afterword: I’d usually put my thoughts on running the module down here, with things I could have improved/changed, etc. But because this post is so long, and this review will be in two parts, with more specifics and spoilers in the second one, I’m gonna split those out into their own post. But yeah, players really liked it, I had a ton of fun running it.
