Read in Short
Anno 117: Pax Romana's first DLC drops April 23rd. It adds a volcanic island called Cinis that's the biggest map the series has ever seen. You'll get new resources, volcanic disasters to deal with, and a temple to the god of fire. Because apparently building a Roman city without the threat of fiery death was too easy.
Look, I get it. City builders can sometimes feel a bit too safe. You optimize your production chains, balance your citizen needs, and eventually everything just hums along smoothly. Where's the drama in that? Ubisoft Mainz apparently agreed, because they're about to drop a DLC that basically says "here's a giant volcano, good luck with that."
Cinis: The Biggest Island Anno Has Ever Seen
Prophecies of Ash introduces Cinis, a volcanic island that expands the Latium province. This isn't just any island though. It's officially the largest landmass the Anno series has ever featured. That's a pretty big deal for a franchise that's been around since 1998.
The island comes packed with plentiful river slots and mining nodes, so you'll have tons of space to spread out your Roman civilization. There's also a brand new resource to play with: Obsidian. This volcanic glass lets you produce carved idols and boardgames, complete with entirely new production chains to figure out.

Playing With Fire (Literally)
Here's where things get spicy. Building in the shadow of an active volcano comes with consequences. The trailer shows giant rocks blasting out of the volcano and smashing into buildings. That's not a cutscene, that's gameplay. Your carefully arranged districts can absolutely get demolished by flying volcanic debris.
- Volcanic eruptions that launch destructive rocks at your city
- Volcanic winters that likely reduce agricultural productivity
- Bloom phases that probably boost crop yields significantly
- New fire safety concerns requiring strategic planning
Ubisoft's press release mentions three distinct volcanic mechanics: eruptions, volcanic winters, and something called a "bloom phase." My guess? The volcanic winters will tank your food production, mimicking what happens when ash blocks out sunlight. The bloom phase is probably the opposite, a period of exceptional fertility thanks to all those nutrient-rich volcanic minerals in the soil.
Temple of Vulcan
The DLC lets you construct a temple dedicated to Vulcan, the Roman god of fire and forge. This building boosts mine productivity and increases your city's fire safety rating. Given that you're building next to an active volcano, that fire safety bonus isn't optional.
Anno 117's Rocky Launch (Pun Intended)
So here's the thing about Anno 117. The game has a "Mixed" rating on Steam, which isn't exactly a ringing endorsement. Part of that comes from a pretty controversial decision to include AI-generated art in the game. Ubisoft has since removed it, but the damage to player trust was already done.
The AI art controversy in Anno 117 connects to broader questions about AI's role in creative industries
There's also frustration about the campaign feeling incomplete. The third act of the story was apparently cut before release, leaving players with an abrupt ending. That's never a great feeling when you've invested hours into a narrative.
But here's the kicker: none of this stopped Anno 117 from having the most successful launch in the series' entire history. Players clearly wanted a new Anno game, warts and all. PC Gamer's Phil Iwaniuk gave it a positive review, suggesting there's a solid foundation underneath the controversy.
What This DLC Needs to Accomplish
Prophecies of Ash has an interesting challenge ahead of it. The DLC needs to prove that Ubisoft is committed to supporting Anno 117 properly, not just releasing content that should have been in the base game. A volcanic island with new mechanics is a good start, but players are watching closely.
✅ Pros
- • Largest island in series history offers tons of building space
- • New volcanic mechanics add genuine risk to city planning
- • Obsidian resource creates fresh production chain puzzles
- • Temple of Vulcan provides meaningful strategic choices
❌ Cons
- • Base game still has mixed reception on Steam
- • Campaign's third act remains cut
- • AI art controversy damaged community trust
- • No word on whether story content will be restored

Release Date and What's Next
Prophecies of Ash launches on April 23rd. If you're already playing Anno 117, this seems like a solid reason to jump back in. If you've been on the fence about the game, maybe wait to see how the community receives this DLC before making a decision.
The volcanic setting is genuinely creative. Most city builders let you optimize your way to a perfect utopia. Anno 117 is now saying "sure, build your perfect city, but also here's a mountain that might explode." That tension between creation and destruction could make for some genuinely memorable gameplay moments.
DLC Details at a Glance
Release Date: April 23rd, 2025. New Content: Cinis volcanic island, Obsidian resource, Temple of Vulcan, volcanic disaster mechanics. Expansion Type: Adds to existing Latium province, not a standalone map.
The Historical Irony
I have to appreciate the historical humor here. The DLC is literally called "Prophecies of Ash" and features a Roman city built near a volcano. Anyone who paid attention in history class knows exactly where this is going. Pompeii and Herculaneum were real Roman cities buried by Mount Vesuvius in 79 AD. Thousands of people died.
Anno 117 is letting you recreate that scenario, except this time you get to try preventing the disaster. Or at least surviving it. Build that Temple of Vulcan, keep your fire safety high, and maybe your little Roman citizens won't meet the same fate as their historical counterparts.
“Building a city in the shadow of a volcano comes with its own hazards.”
— Ubisoft, stating the obvious but also the entire point of this DLC
There's something weirdly compelling about that premise. City builders usually let you build toward perfection. This one is asking whether you can build toward survival instead. Can you create a thriving Roman settlement knowing that volcanic eruptions will periodically wreck your stuff? That's a fundamentally different design challenge.
Should You Care About This DLC?
If you enjoy Anno games, yes. The volcanic mechanics sound like they add genuine strategic depth rather than just being a reskinned disaster system. The new production chains around Obsidian will give you something fresh to optimize. And honestly, the Temple of Vulcan sounds like it could become a crucial strategic building that changes how you approach the entire map.
If you bounced off Anno 117 at launch due to the AI art or incomplete campaign, this DLC probably won't change your mind. Those issues stem from the base game, and Prophecies of Ash is adding new content rather than fixing old problems.
Tech companies continue pushing boundaries with AI integration, sometimes controversially
But for everyone else? A Roman city-builder where you're constantly negotiating with an active volcano sounds like exactly the kind of creative twist this genre needs. April 23rd isn't far away. We'll see if Prophecies of Ash delivers on its explosive promise.
