I Was Travelling the Planes and I Found Dragons

Hello and welcome to the first planar dragons article. This article is planned as the first of a series. In this post I’m presenting the 5e stats for adamantine dragons. Please leave comments below on how to improve this article and I’ll try to take them on board for future posts. Also, at the end of the article, I’ll be revealing what dragon I’ll do next; so if you have any art on that dragon a link to it would be appreciated. Thanks and enjoy.

Defenders of Bytopia. Adamantine dragons don’t inhabit the material plane like most other dragons but they reside on the plane of Bytopia. They patrol throughout the plane, ever on the watch for invading fiends, spying rilmani and other unwanted intruders. Rarely does an adamantine dragon lair in the uncivilised Shurrock, due to their preference for company, but some do in order to protect travellers. Some adamantine dragons reside on the material plane near portals to their home plane, trying to protect them from threats such as gnolls and evil wizards.
Gnome friends. The gnomes who live in Bytopia, the closest allies of adamantine dragons, create the castles which the dragons use as their lairs. The castles are usually constructed near gnome towns. When the gnomes finish building the dragon’s lair, it swears to protect the gnomes with its life. A part of this unspoken deal is that the gnomes will farm the land and give the dragon some of their slain cattle. Only one thing will cause an adamantine dragon to turn against the gnomes that built it’s castle: if the castle is destroyed, the dragon will go on a rampage lasting years, hunting down whichever mortals dared attack it’s home.
Metal hoarders. The hoards of adamantine dragons are often filled with precious metals. The dragons favour adamantine and mithril over other metals. One thing favoured more than precious metals is magical weapons and armour, with special preference going to sentient weapons and armour. Sometimes adventurers will travel to a dragon’s lair to request a piece of armour or weapon and the dragon will often grant such a request if the it believes the adventurer’s cause to be just and good, but the weapon must be returned after it is used. Most adamantine dragons also have a scrying pool which they use to compare details on invading fiends and other threats. This is the most sacred of treasures that a adamantine dragon has. Only one gnome has knowledge about this sacred room, usually the one that built it.

Ideas for campaigns

  • The PCs all play gnomes building a castle; if you have the PCs searching for rear materials, defending from monsters, buying materials and even drawing a map of the castle you could make a campaign out of it. Pathfinder also has some good rules for constructing buildings.
  • The PCs are searching for a weapon or piece of armour, at some point during the quest they find out that an adamantine dragon has it in his hoard. The quest can be focused on reaching the dragon or fulfilling a request for the dragon so that he will give the PCs the item.
  • An adamantine dragon’s castle has been destroyed and is going on a rampage, maybe an adventuring group destroyed it (deliberately or not) or it was destroyed by the PC themselves.
  • Fiends are coming into Bytopia and an adamantine dragon is requesting help to fight the fiends off, will the PCs help it?

Remember, it’s a good dragon, so unless you are playing an evil campaign you’re not going to want to kill an adamantine dragon, and are more than likely to be working for it.

LAIR ACTIONS
On initiative count 20 (losing initiative ties), the dragon takes a lair action to cause one of the following effects; the dragon can’t use the same effect two rounds in a row:

  • Up to 3 sets of armour animate and attack, use the stats for animated armour. If the pieces of armour have any special properties they gain them when they animate; for example if a set of armour is made out of adamantine it reduces critical hits to normal hits. They fall to the ground unanimated when this lair action is used again, or after 1 hour.
  • Up to ten tapestries that the adamantine dragon can see burst into flames, though they remain undamaged, any creature touching them takes 2d8 fire damage. The tapestries are snuffed out on initiative count 20 the next round.
  • The ground starts to move as if a liquid, though creatures don’t sink through it. The ground is treated as difficult terrain, until initiative count 20 next turn.

REGIONAL EFFECTS

  • Small beasts in the surrounding area, up to a range of 3 miles are more friendly then normal creatures, and can act as the dragon’s eyes and ears.
  • Gnomes in the surrounding area up to a range of 4 miles are more friendly, so I guess nothing really changes with them, but they will be helpful to a fault.
  • Within a 4 mile radius the save DC against the alignment change unique to Bytopia is 15 instead of 10.

The creature effect ends as soon as the dragon dies, the save DC changes back to normal in 1d4 days, the gnomes change back to normal in 1d10 years.

Dragonborn. Adamantine dragonborn have resistance to fire damage, you also have a breath weapon that deals fire damage in a 5 by 30 ft. line (Dex. save).

Adamantine guard drake. A adamantine guard drake has resistance to fire damage, and whenever a adamantine guard drake uses its bite attack it deals a extra 1d6 fire damage.

So that’s my go at the defenders of Bytopia, have fun with them in your campaign. My next post will feature the Elysian dragons, the drunks of the dragon race.

  • Neat! I like the inclusion of a dragonborn entry for PCs, simple and for completeness’ sake. A planar dragonborn from Bytopia is a fun character concept. I look forward to the Elysium dragons!
