Ice Volvagia and Fire Volvagia.

[Master_of_Power]

Triplealso: there are two scripted minibosses - Ice Volvagia, and the Rival (who defeats a monster called Fire Volvagia just as you enter her room). Both of the dragons are actually the extended elemental heads of an unseen Trinexx, who bursts through and swallows the Rival when you "defeat" her.

This is what I was talking about, Shadow Tiger.
