EB-16 The Dragon Below



In the depths of Valaara's sanctuary, the Order of the Emerald Claw harnesses ancient engines of destruction to wage war on the surface world. Only the Oracle of War can stop them now - if the adventurers can get it to work! Optimized for APL 16, this is the third in a trilogy of adventures, the Engines of War storyline.

Welcome to the Oracle of War campaign, a new 20-part standalone story for the D&D Adventurers League! You can play this adventure as part of your own Eberron: Rising from the Last War campaign, or as part of the Oracle of War organized play campaign. While this campaign runs under the umbrella of the Adventurers League, it utilizes different rules. You can familiarize yourself with these unique campaign rules by checking out the Oracle of War Player's Guide and Oracle of War DM's Guide, found in the D&D Adventurers League Players Pack.

Really cool campaign, been playing on Shard VTT with my group for the past few months.

Been a little tricky to run at times but fun - as DM I didn't / still don't really know 100% what is going on either! There are a few parts that I would have modified if I would have known more at the time, but nothing major. My group is currently on part 11, and I've skimmed up to 16.

I encourage DMs to check this out - it's fresh, great Eberron feel and story.

Really, really hope it continues on schedule without delays monthly and 20 is out first week of Sept 2021. Earlier would be ok too lol. As it stands going to have to slow things down.

Not sure on all the legal mumbo-jumbo, but when completed if this was ever bundled up and compiled into a full length book / campaign I would throw down for it without hesitation.

Hey Steven, thanks for the kind words! Glad to hear you and your group are having fun with the campaign.

We're committed to releasing a new episode every month although the release dates within each month sometimes do slip due to playtesting / premiere availability (next month's Epic, for example, is likely to release toward the latter half of the month).

My plan is to compile the whole thing into a single volume when it's done, but unfortunately I can't promise it - there are a few hoops to jump through. We will definitely offer a bundle deal and include a campaign summary though!

- will there be 2 releases in June (Epic and EB-17)? Or do you mean that Epic is June and EB-17 will be July ? That would push finale into October (noooo!)

- read discussions on last few adventures, agree 100%. It would be great if each remaining adventure had short DM info at the end with any update on events, NPCs etc. Know space is tight but even few lines is helpful. Sky Blue is most obvious example - introduced in 7, few cameos but will be back in 20!? That's helpful info, don't really needs specifics at this point but very good to know.

- is there a way to be part of playtest? I'd be down for that!

Epics are part of the core campaign, so they use a monthly slot. This ends the campaign in November (as we also have EBEP-04 to come!).

If you want to be part of the playtest teams, I suggest you mail

Could you please explain why the Emerald Claw has an interest in releasing Valaara? How does this slot into the goals of the Emerald Claw?

Why is the Gatekeeper seal connected to Dolurrh? What does Dolurrh have to do with the Gatekeepers, Valaara, or the daelkyr in general?

Why is it supposed to be a viable option for the PCs to release Valaara, if that is exactly what the Emerald Claw wants to do?

Also, I was under the impression that Mabar was the plane full of negative energy, not Dolurrh.

The Emerald Claw has no interest in releasing Valaara. If you read Trez Zul's letter in EB-14, it's pretty clear he's only interested in plundering the symbionts and unlocking any other "secrets" held within the sanctuary. It's a treasure hunt. The Emerald Claw know that a daelkyr is trapped within (see the evidence board in EB-11), but they don't even know which one. Zul breaks the seal out of nothing less than ignorance and greed.

The Gatekeepers drew on unknowable magic to create the seals. This particular one was imbued with the spirits of the dead, forming a link that draws on the power of Dolurrh.

The PCs can release Valaara if they really want to, primarily to crush the Emerald Claw. Question is - do they trust Spinweave?

Mabar and Dolurrh both are negative energy-oriented. However, as Dolurrh is the realm of the dead, it is also very soul-oriented which is why it has connection to the seal.

Is "ignorance and greed" really the best motivation for the end villain of an entire high-level adventure arc?
Customer avatar
Theresa O May 05, 2021 9:39 pm UTC
To be clear, I find that the "ignorance and greed" demonstrated by the villain here is of the crude, "not even placing an ounce of thought into the matter" variety.

Will D May 05, 2021 10:29 pm UTC
Ignorance, almost by definition, involves putting little thought into the matter, and greed is a powerful motivator that seeds rash behaviour. I think you'll find human history is littered with powerful figures who have fallen victim to both!

Is knowledge of Valaara obscure enough that all the insects are insufficient to tip off the Emerald Claw to the identity of the daelkyr there?

I think it takes decent execution to present an arc finale boss whose plan is very short-sighted and stupid, and I do not think the execution here is particularly satisfying, or well-explained. "The villains simply did not think this through" can, at times, come across as the writers being unable to coordinate themselves and devise a smart villainous plan; this is one of those times.

I’m sorry you feel that way, Theresa :)

This is a campaign about slowly unraveling a conspiracy; I would expect the payoff of the reveal to be more than just "the villains were just stupid," particularly at so high a character level.

As I said above, Trez Zul’s motivation has been pretty clear since the first adventure in this trilogy. He wants to plunder the sanctuary for its symbionts. There’s no real mystery there.

The players’ motivation is to find out from Zul where the Lord of Blades has taken the Oracle of Bones. As they play through, they learn that the Emerald Claw is accidentally stirring up something terrible - something that imperils the whole world.

This arc of the campaign is very much inspired by Indiana Jones, with the Emerald Claw filling the role of Belloc and the nazis. Just like the movie, the villain’s goals are intentionally simple - foolish power and greed.

Clearly, the execution of the arc didn’t land for you. I will defend the premise though.

I couldn't find anything in canon that supports Dolurrh being negative energy-oriented. Indeed, Eberron: Rising from the Last War states that the source of negative energy is just Mabar. Can I ask where you're getting that idea from? Is it just because that's how a plane of the dead would work in any other setting?

Just a note that the third Epic - EBEP-03 The Rising City - is designed to slot it between EB-15 and EB-16. It's optional, but details the group's journey through Metrol and infiltration into the Creeping Nave.

If all goes well, we'll release it next month. If you want to play EB-16 first and then run a flashback to EBEP-03, AL players should decline leveling out of Tier 3 on completion of EB-16.

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
