Are there Dragons in Athas other than the Sorcerer-Kings?
If so…what do I need to know about them?

No Johnny, there are only the Sorcerer Monarch type dragons. While being a Sorcerer Monarch is not a prerequisite for the metamorphosis it does help and explains how someone acquired knowledge of the spells needed.

However, this is likely to change in 4E.

What’s likely to change, the fact that there is only one dragon type on Athas or something else?

The only dragon-like athasian monsters are elemental Drakes. In some 2ed manuals they mentions that Wyverns exists in Athas.

No true dragons exist in Athas. Dregoth used true dragon’s bones in the buildings of New Giustenal, but they’re from true dragons that he killed in his interplanar travels.

There is the Dragon from Black Flames adventure. He wasn’t a SK. Can’t recall his name though. Begins with an “E” if I’m not mistaken.

Farclunn? Or something like that. I believe the idea was that he was a defiler who figured out how to start the metamorphosis, but didn’t have the ability to grant spells to Templars (pristine tower and all that).

The idea was that he was trying to stay hidden while gaining power.

“There is the Dragon from Black Flames adventure. He wasn’t SK. Can’t recall his name though. Begins with an “E” if I’m not mistaken.”

Yes, his name was Farcluun. He was an upstart defiler/psionicist who’d reached the beginning of dragon transformation. Dote Mal Payn, former necromancer to Kalak, is listed in “Faces of the Forgotten North” as another upstart dragon.

In addition to dragon transformation, you’ve also got some clerics who can take the “Drake Guardian” prestige class and over time transform themselves into “half drakes” (detailed in “Terrors of Athas”). I’m not sure if they can become full drakes at epic level, but I wouldn’t be surprised.

And then there’s the Dray, which are humans that are transformed into dragon-like humanoids by the undead sorcere-king Dregoth in his effort to create a “perfect race”. There’s some indication that these will be the Dragonborn in 4e Athas.

Oh yeah – and along with drakes, there were several other dragon-like monsters in 2nd edition. There were wyverns as noted above, and also the dracolisk (giant basilisks with pertrification gaze), behir (dragon-like creature with 12 legs that breathes lightning), and dragonne (dragon/lion crossbreed with a roar attack). Not sure if these are included in later editions of the DS setting…

I want to remind also that the lay people of Athas believe there is only – 1 – dragon. Only a very select few know of the dragon metamorphosis or the Sorcerer Kings’ transformations.

Overall, there are very few ‘sentient’ monsters on Athas. Most of them are just hungry and/or thirsty.

I think this is likely to change in 4E because the trend seems to be to shove ‘everything’ into the setting (ie Tieflings, Dragonborn… we fought goblins in the last D&D Encounters session)

“Overall, there are very few ‘sentient’ monsters on Athas. Most of them are just hungry and/or thirsty.”

Really? I’d have to look back at the random encounter charts to verify this, but when I played back in 2nd edition, it seemed like most of the monsters you encountered were sentient. Besides the plethora of npc humanoids (gith, belgoi, braxat, giants, mountain stalkers, ssurans, tareks, dune freaks, b’roghs, hej-kin, t’chowb, etc.), I believe that the drakes, flailers, floaters, mastyrials, kirre, and klar all had at least “low” (5-7) intelligence, and others like the gaj, id fiends, feylaar, jozhal, scrabs, tembos, and dark spiders all have “average” (8-10) to “high” (11-14) intelligence. It got kinda ridiculous, so I house-ruled several of them back to “animal” (1) or “semi” (2-4) intelligence.
