The Weirdbat is a distinctive undead chimera that once prowled the swamps and ruins of Highmarsh. This fearsome creature is notable for its bat-like appearance, featuring pointed ears and a pair of massive, leathery wings. Unusually, it also possessed an additional set of functional limbs, each armed with razor-sharp claws. Its skin had a silvery sheen, particularly under moonlight, which added to its eerie presence.
The adventuring group known as the Travellers encountered the Weirdbat while journeying through Highmarsh. Using echolocation, the creature detected their approach, leading to a fierce battle. After a hard-fought struggle, the Travellers managed to slay it. Upon closer examination, the group discovered that the Weirdbat was more than a simple giant bat—it was a grotesque chimera, assembled from various animals and beasts. Varis Brightheart, one of the party members, dissected the creature, revealing it had two distinct hearts. This discovery led them to suspect that the Weirdbat was a creation of the notorious dark alchemist, William Vicarin.
