Archelone

Once in endless swamps of the Mire Wyatt, Viendrion and his sister Archenar were flying and fighting different monsters, but then... Archenar was lost during fight with one of monsters who inhabited the land, and was found by a wartoad that brought her to her kind.

She united her powers with a Plague dragonet called The Lone found here, and together they mutated to something bigger... to Aberration!
The legends telling wartoads had some Wyrmwound essence were true, and living with them resulted in turning into stronger dragon. As she evolved enough, Archelone left the wartoads and came back to lair.

Archenar, the head with third eye, has an ability to create a poisonous goo-like web she uses in combat.
The Lone, the head with roundhorns, is able to breathe with noxious green smoke.
All their abilities are result of Wyatt once hit the wartoad with Envenom ability, and mutating dragonets devoured the power during evolution and shaped it into their abilities. That's why they help Wyatt with exploring and testing new spells.

Archelone is fond of stories and likes telling them. The Wilderness Wanderers who often visit their lair get some inspiration thanks to her. Sometimes she travels with them to evolve in the Wyrmwound and travel back to the lair.
