Yellow-eyed Bird
The result of the union between an old bat and an owl, the yellow-eyed bird is a mythological creature from Cantabrian traditions. Its characteristics suggest some relationship with the basilisk, as it shares with that creature certain traits, among them the ability to kill with its gaze alone. However, it is less lethal, because this power is not permanent; rather, the gaze must occur while church bells are ringing.
The gaze of the yellow-eyed bird is so intense that it burns the entrails of its victim, causing death within a span of four hours.
This strange being does not appear during summer, and because it possesses blood similar to oil, its weakness is a fear that the sun will heat its blood.
