Wyrm

Acidic Tyrant of the Swamps

Black dragons rule the dismal swamps and decaying wetlands with malice and cunning. Their pitch-black scales, twin curved horns, and acid breath define them. Their corrosive breath dissolves even steel armor instantly. Notoriously cruel and sadistic, they prefer torturing prey slowly rather than killing outright. As amphibious creatures, they nest deep in murky waters and often keep human slaves to maintain elaborate underground lair-mazes within their territories.

Hydra · Lernaean serpent — Multi-headed mythical beast

The Hydra (Ὕδρα) is Greek mythology's most famous multi-headed monster, dwelling in the swamps of Lerna near Lake Lerna — hence its precise name 'Lernaean Hydra.' According to Hesiod's Theogony, born to the monstrous Typhon and Echidna, with nine heads (varying by tradition: 7, 100), the central head being immortal. Its most terrifying ability was that when one head was cut off, two grew back in its place — an absolute opponent that could never be defeated by simple force. The target of Heracles's second labor, Heracles defeated it only with his nephew Iolaus's help, immediately cauterizing each severed neck with a torch to prevent regrowth, finally sealing the immortal central head beneath a massive boulder. Its blood was used to coat arrows as eternal poison.

The Tyrant of Flame

The most iconic and feared entity in Western fantasy, the red dragon is recognized by its crimson scales, massive bat-like wings, and devastating fire breath. Adults reach 20-30 meters in length and are famous for their obsessive hoarding of gold and gems, often depicted sleeping atop vast treasure piles. Possessing extreme intelligence, ancient cunning, and command of high magic, they demand tribute from human settlements within their volcanic territories. Their lives span over a thousand years, and the oldest specimens are considered living disasters in their own right.
