Eberron: Random Tables for Shargon’s Teeth

I’m currently running a 5th Edition game in Eberron. The PCs are sailing across the Thunder Sea, past Shargon’s Teeth, to Stormreach and Xen’Drik. Of course, bad things are happening, and it looks like they’ll end up stranded on one of the islands of Shargon’s Teeth, possibly island-hopping their way to Stormreach.

Or they’re going to defeat a Marid as a 4th level group – 5th Ed is crazy.

I like having random tables – they actually help me with creativity when I need to do something like come up with a bunch of interesting but variable islands. If all of the options on the tables are interesting to me, then what becomes interesting are the surprise interactions. I didn’t always like them, but I’ve changed in the last few years.

I’ve come up with some random tables  to use in creating islands in Shargon’s Teeth. Part of my thinking here is to treat Shargon’s Teeth kind of like different versions of Galapagos islands. At least, I’m using the Galapagos as inspiration for the Teeth (as I’m using Madagascar and New Guinea as inspiration for Xen’Drik).

First is a random table of unique elements for each island. These are the first thing you’d notice about the island, and form the core of how I describe it:

Random Island Features: Shargon’s Teeth

Roll d10

  1. Easily accessible fresh water
  2. Barren and dry; water from fruit and coconuts and rain
  3. Plenty of coastal food, shellfish, shoals
  4. Brutal sharp coral surrounding the island
  5. A high peak at the center for long visibility (if climbed)
  6. Crumbling ruins of a lost civilization
  7. Island formed around the ruins of a massive, ancient ship
  8. Coral atoll surrounding a deep blue hole
  9. Groves of dragonsblood trees (Socotra Island)
  10. Sharp, steaming volcanic activity (steam and magma mephits)

Next, I have a random table for the dominant living thing on a given island. I’m thinking of the islands having some basic island plants and animals, but there’s one dominant living thing, taken from this list:

Random Island Megafauna (and Megaflora): Shargon’s Teeth

Roll d10

  1. Giant marine iguanas
  2. Giant tortoises
  3. Carnivorous pisonia trees
  4. Giant racer snakes
  5. Giant ironweb spiders
  6. Basilisks
  7. A water weird
  8. Swarms of stirges
  9. Giant crabs
  10. A Pseudodragon

Last, I have whether there are intelligent inhabitants on the island. There’s a one third chance of each island being uninhabited by any intelligent creature, and then some interesting options:

Random Island Inhabitants: Shargon’s Teeth

Roll d12

  1. No one
  2. No one
  3. No one
  4. No one
  5. Sahuagin outpost
  6. Sahuagin outpost
  7. Locathah living in a blue hole, self-sustaining and hidden
  8. A subterranean, underwater cult of kuo-toa
  9. Feral victims of a previous shipwreck
  10. Escaped sea spawn
  11. Lizardfolk
  12. Sea hag

Obviously, these are specific to Shargon’s Teeth, and may not translate to any other particular setting. But I really like these as a starting-point for these particular islands, and I hope the PCs end up island-hopping for a while.

I also created a big random event and encounter table to keep the journey interesting. The results weren’t quite what I’d hoped, but I think I tried to cram too much into the voyage, including testing out Xanathar’s Guide’s downtime rules during the voyage and having some intrigue as well.

As often as you’d like, have a player roll a d100 and consult this table. Not all of these are supposed to be combat encounters – none of them were for our game. Rather, they were glimpses of a larger and sometimes scarier world:


1-4 Huge marine iguanas

5-6 Water elemental

7-8 Air elemental

9-10 Kraken

11-20 Sahuagin patrol

21-22 Dragon eel

23-24 Dragon turtle

25-26 Giant octopus

27-30 School of giant squid

31-35 Soarwood ship

36-46 Ship – roll to determine if it is a pirate

47-48 Wind galleon

49-50 Lyrandar airship

51-55 Pod of whales

56-60 Dolphins at the prow

61-64 Merfolk at the prow

65-67 Dragon (black, green, bronze or gold)

68-69 Stirges

70-80 Becalmed

81-91 Thunderstorm

92-93 Roc

94-95 Steam or ice mephits

96-97 Plesiosaurus

98-99 Coelacanth or other huge archaic fish

100 Roll twice

5E Eberron Campaign

Setting Sights Additional Eberron Dungeons Dragons | Apps ...

I’m currently starting up a 5th Edition Eberron campaign. I have a lot of the books from the original version of Eberron in 3.5, and therefore more fluff than I could ever use, but it will take some adaptation to run this game. Unearthed Arcana has released some updates for basic Eberron material, which I am taking as my starting-point.

House Rules

First, some house rules. I can’t seem to run any RPG without at least a few house rules, and D&D is no exception.

Players roll all the dice. I just like this way of running a game, especially a game like D&D. I feel like the game slows to a crawl whenever the DM needs to roll dice for all the monsters and NPCs. Basically, where NPCs have bonuses I make those DCs, and where PCs have DCs (like Armor Class) I make those bonuses. I also use set damage, as in the MM. (Bonus: based on our first session, this rule works amazingly well, and is now how I DM)

Let it ride. I use this rule in all of my games. I get it from Burning Wheel. Basically, once you roll for something, the stakes remain. One stealth roll to sneak all the way in the castle. One roll to pick the lock. You can’t make another attempt until the conditions change.

Action points. One element of Eberron is Action Points. To emulate those in 5E, I just made the simple change that players can store, and swap, points of inspiration. Over time they can build up, and have a similar function to Action Points.

I’m also going to be working on house rules for House Tarkanan aberrant dragonmarks and the effects of the Mark of Vol, which I will share when I have them.


Everyone’s hack of D&D 5E to run Eberron will be a bit different. Here is what I have in mind for my own: in the Eberron setting material as written, as usual for 3.X D&D, the NPCs often have PC character classes, sometimes mixed with NPC classes. 5E’s approach from the Monster Manual and onward seems to be much more about exception-based design, including for humanoids who have abilities very similar to player-character classes.

One thing from Eberron that I’ll retain is that there are not many high-level NPCs in the world. So you get a setting where tons of characters have first-level spells of various kinds, and spells are relatively common up to maybe 3rd level, but if you need someone resurrected you’ll have to go on a question to find some sort of religious figure who can help you out. There also end up being plenty of threats that only the PCs can really deal with in the world, as CR 20 monsters abound.

Obsidian Portal

I love using Obsidian Portal for campaign management. It’s a good way to have a lot of my worldbuilding notes right in front of me, to track player-characters and NPCs, and to have something cool for players to dig through looking for Easter eggs that will help them in-game. This is my Obsidian portal page for Shadows of the Last War.

They Didn’t Meet In A Bar

To introduce the characters to one another, I threw them into a pretty contrived fight scene where some of their backgrounds came out all at once. After that, though, I had to have a reason for them to be working together. I hate the stage in a game where the PCs are pretending not to want to work together, so I decided to just force them together early on, and the players were OK with that. Sharn gave me an option I hadn’t used before – because of the high rent in Deathsgate where they all wanted to live, they are roommates. So now it’s a sort of dysfunctional episode of Friends, and the players all introduced their characters to each other by answering the question, “What kind of roommate are you?” It went great, and I recommend it as something to have in the goodie-bag for ways to get the party together early in a game, especially an urban one.
