Druïde Vampiric Dragon

The Nightcrown Basiliskdrake

More reptile than dragon: a low-slung, muscular nocturnal hunter crowned with black wood and bat-like wings.

For TTRPG:
Druidic twist: it melds into shadow-trees; its scales become bark.

Vampiric twist: its gaze causes “blood-stasis” (a slow/immobilize-like effect).

Iconic image: behind it, deadly bellflowers grow and snap shut on their own like traps.
