They look like cat dragons, but the name Managarmr (Hati Hrodvitnisson) in Norse Mythology is “Moon Dog” representing a dog/wolf that chases the moon and will consume it upon Ragnarok. (Just as Sköll chases the sun and will do the same.)
Inside the hollow pile of wood, clay and snow there was a small fire, as well as a hole in the wall filled with dead salmon frozen in ice, and another with several sections of mammoth tusks carved with symbols in draconic, which the rock drake instantly picked up in her claw and started reading.
"Who are you?" The black wyvern asked, "who are you?" Lupus replied "I'm Obsidian, and the rock drake is Bluefeathers"
"I am Lupus" Lupus said.
Just then, a small lizard with a very dim light at the tip of it's tail crawled out of the rock Drake's head feathers and over to the fire, where it lay down on a mammoth hide and went to sleep, it's light gradually getting brighter from the heat. "What is that?" He asked, "my glowtail, Glowyrm" Bluefeathers explained "rock drakes keep them for pets and messengers"
"Ah, managarmrs raise one of their namesake animal"
As he said this, a direwolf that had been lounging on a deerskin sat up and walked over.
The moths started biting the wyvern furiously, until all that was visible was a massive blue light, then, the moths cleared, but of the heir there was no sign.
"Why did the moths eat the heir though?" Obsidian asked
"It harmed the tree that gives them food, they defend the tree against anything that could be a danger to it, and it was full of blue glow as well" the drake replied.
"We should get out of this cave before more heirs come though, these moths won't be able to eat them all" going out of the cave, Lupus charged his combustion chamber and leapt towards the distant green smudge on the horizon. They went on for another few days, though there weren't any more of the blue moths, or crystal heirs, thankfully.
When they got to the crystal jungle, they saw a pair of large purple eyes in the shadows, slowly out of the shade came two bright pink wyvern wings, followed by an acid-green head with pink crystals rooted in the back.
"These moths seem to be bringing whatever is glowing to this tree in return for food from it" Bluefeathers said, just then, the sound of water rushing followed by a hiss of steam echoed through the cave "TROPICAL HEIRS!" Bluefeathers said, quickly camouflaging and scuttling towards the sound, Lupus followed the rock drake, to find a green crystal wyvern at the entrance, steam rising out of it's mouth.
Obsidian was nearby, getting ready to flame the wyvern, the wolf, still glowing blue, leapt at it, as the wolf bit the heir, the blue glow spread into it's scales, "wait! I have an idea, get the heir into the cave with the tree!" Bluefeathers's voice said from somewhere to the left,
Doing as they were told, Obsidian and Lupus pushed the crystal wyvern, then ran into the tunnel with the tree, the crystal wyvern looked around for them, and it's tail hit a branch of the tree, snapping it off...
Then, suddenly, all of the blue moths in the cave flew at the wyvern,
Lupus looked around the cave, the tiny blue moths were flying out of a large hole in one side of the cave, into a tiny tunnel in the cave wall, then going back away again glowing much brighter. "There's something in the wall that's giving these moths energy" he said, Bluefeathers walked over across the ceiling, "hmm... You're right" the rock drake said, the wolf padded over and sniffed at the hole, as it did so, it's fur started glowing electric blue, the same colour as the moths.
"Interesting... Whatever is making the moths glow works on other animals too" Bluefeathers said, "I wonder where the moths are going back to" climbing down onto the floor, the rock drake followed the moths into the larger hole.
Inside the tunnel, there was a single massive blue tree, covered in blossoms glowing the same blue as the moths, as Lupus watched, the brighter moths crawled into the flowers and came out glowing dimly, but flying much more energetically.
Lupus looked out over the huge rocky plain that separated the four draconic territories from the southern edge of the lunar tundra, his direwolf, Bluefeathers, and Obsidian were nearby.
Charging his combustion chambers, he leapt out of the tundra, the wolf ran behind him as Obsidian flew overhead and Bluefeathers hopped and glided between trees and stones,
Bounding southwards, he quickly noticed how warm it seemed, having spent his entire life in the cold of the lunar tundra.
After they'd gone on until nightfall, Obsidian said "we should find a safe place to stop for the night"
"Yes" Bluefeathers replied, Lupus nodded, "a cave with a small entrance but larger inside would be good"
After about an hour searching for a good cave, they found a cave with an entrance just big enough for a wyvern, that opened out on the inside into a large chamber filled with small glowing moths, which Glowyrm started catching and eating by luring them in with his light
"What?! Where?" Smilodon said, her sabertooth looked up from the salmon it had been eating, "near the stream, it came from a grove of pine trees" Bluefeathers replied, Lupus charged his combustion chambers and bounded towards where the rock drake had said that the yutyrannus attacked, after a few minutes he got there and saw Argent fighting the feathered beast with a trio of carnotaurus assisting it.
His direwolf growled at the creature, fangs bared, as Bluefeathers and Sabertooth arrived.
Rushing one of the yuty's carnos before it had time to react, he bit it's tail to distract it as his direwolf leapt and broke its neck with a swift bite.
Bluefeathers had been camouflaged up until then, but now she blipped into visibility high in the air before crashing down on the second carnotaur, taking it completely off guard, she bit at its head until it died, then Smilodon's sabertooth ran over the snow towards the third carnotaurus. Which turned to face the cat
Lupus blasted over the frigid landscape of the lunar tundra, searching for prey, Argent, Smilodon, and the animals nearby.
down below He saw a megaloceros stag eating a small patch of grass, diving out of the air, he landed on the deer with a crunch, breaking its neck.
Picking it up in his mouth, he Leapt away back to the managarmr village.
When Lupus got to the village he found Smilodon sitting at the larder with her sabertooth, a muscular black creature with a scar across his snout. "Where are Argent and his argent?" He asked, "I don't know, probably still chasing something" Smilodon replied, just then the rock drake Bluefeathers returned from hunting with her glowtail, who appeared to be wearing a sort of mammoth-fur tube with holes for it's legs and head on her shoulder.
The rock drake dropped a group of dead pegomastaxes onto the snow, "Argent's being chased by some feathery creature with a pack of carnos!" She said
Lupus looked at the wyvern and rock drake, wondering whether to freeze them to death or take them to the village for the others to decide,
Eventually the strange newcomers piqued his curiosity.
"Come on then" he said, "any moment more and the direwolves will get us".
As he said this, he started to secrete flammable gas from the glands in his hind legs into the combustion chambers in the soles of his paws, building up the pressure until the gas ignited and launched him into the sky in an explosion of snow and blue flames.
The wyvern and the rock drake started following him as he bounded across the landscape, eventually they came to a group of what appeared to be slightly pointed piles of snow, some much larger than others. Brushing away some snow from a large one with his snout, he opened the concealed door made of pine branches stuck together with mud and went inside.
Lupus reached the hill where the managarmrs and ice wyverns held gatherings, when he got there it was already crowded with managarmrs, ice wyverns, and various tundra animals, mostly wolves and sabertooths, argentavis and megaloceros were more rare, while mammoths and yuties were almost absent.
The managarmr leader, a large black furred male
managarmr-ice wyvern hybrid with a white yutyrannus,
leapt onto the hill.
"A black wyvern has told me that they are attempting to stop the attacks by crystal heirs, however they need one of each species of draconic, including one managarmr" the managice-wyvern said,
"A managarmr will have to be chosen to go to the crystal jungle"
As the last carnotaurus prepared to attack the sabertooth, Smilodon fell out of the sky onto its back, crushing it.
Argent's argent swooped out of the sky and pecked at the yuty's eye, disorientating the creature, as Argent moved onto his tail and wings, using his hind legs to blast flames at it.
Streaks of blood started appearing on the yuty's back, moments before Bluefeathers uncamouflaged on it, Smilodon bit at the creature's legs, then Lupus blasted himself into the air and shot an ice-beam at the yuty.
The feathered menace roared and fled off into the snow.
After the yutyrannus was gone, they walked back to the village, Lupus, Bluefeathers, and Argent's argent carrying the dead carnotauruses.
Back at the village, messenger-argies were flying around, dropping messages on thin strips of megaloceros skins from their beaks and talons, "quickly! This means something important is happening!" Lupus said to the rock drake.
