Next session won’t be sooner than next month. Summer is Garden Time and my already sparse gaming schedule always take a big hit. Anyway, I’m still doing some prep in advance.
Next session: The PCs are going south on the Olung river. They’ll have a few river encounters en route, one that is set with the events of last session (can’t talk more about this for the moment!). They are on board of the Inexorable Barge, a magical boat that can cross the steepest of riverfall without a sweat, so they’ll advance at a steady pace without having to do perilous portage.
One major site that can be found along the way is the Gardens of Nangalore. It’s a location that comes from Tomb of Annihilation, one of the good ones, that I’ve modified/expanded a lot (still working on this). The PCs know that explorer Castigliar lost his life while exploring the site. They also know that there’s some kind of powerful demoness or sorceress at the heart of this place. They don’t need to go there. They do have a few incentives to explore it though, we’ll see if they will be tempted…
They’ll eventually reach Lake Luo and from there, they’ll have to find the Star Princess airship or its crew kept captive by pterafolks, or both.

Does the river look like this?
It’s not very clear from the ToA book what the Olung (or any other rivers) look like.

Or like that?
A tendancy that I’ve seen often in rpgs is to downsize things just so they’ll fit a hex map or a decor prop. There’s moments when Theatre of the Mind is the way to go, but you have to first visualize what you’re gonna describe to the players!
Here’s a link that I thought was very useful:

I’ve learned that a section of the Congo river is called the « Gates of Hell », a « 75 miles long canyon of impassable rapids ». That’s pretty impressive. Another case of Nature being more awe-inspiring than fantasy.
Which is one reason why I garden instead of gaming. See ya!
