So, the latest first session ended with the dwarven slayer imprisoned in a demiplane of nothingness with Balaur, a mighty dragon. Here’s him and his three brothers:
Balaur, the green dragon, lord of earth, forests, rivers, poisons and diseases; it’s the most deadly one. Three heads, amphibious, burrowing but flightless, similar to a giant crocodile, full of horns and fins, covered in vegetation, moss, mushrooms and parasitical beings.

Vishap, the blue dragon, lord of seas, lakes, skies, winds, storms and lightnings; it’s the most destructive one. Body of a very long snake, third eye in the forehead, six rapacious legs, four feathered wings and a horned, fanged beak.

Kulshedra, the red dragon, lord of mountains, caves, fires, volcanos, and smoke; it’s the most evil one. Classic dragon body, bat wings, lion mane, beard and other hairy stuff around, fangs and horns everywhere, two giant snake heads coming off his tail.

Dragons fought against the dwarves in the war of ages; the latter eventually killed all of the dragon mothers. The dragon warriors’ vengeance was terrible, but the war ended with no winners, the dwarves decimated, the dragons totally without females. But while the dwarves grew strong again in time, the dragons faded one by one, killed by heroes, by other dragons, or just falling in eternal slumber. Only these three are known to be alive and active by the wisest ones.
