In my epic fantasy I have four races of creatures which were all hunted down due to their valuable blood which grants the drinker magical abilities (premonitions). After time they all became extinct or near extinct. I want an explanation by which these animals could have been all wiped out. They all live in different continents which makes it hard. Your suggestions don't all have to be similar, they can be different ways to hunt down different creatures.
I have 4 species of creatures, and only a few specimens of each are left alive:
- A giant ape like creature in the desert: only 2 left.
- A bird like creature that is similar to a dodo (Raphus cucullatus): only 3 left.
- A giant vicious bear-like creature which lives in the snow.
- A giant sea creature.
All of these animals are vicious.
There is obviously magic in my world, but only ESP/visions, nothing that would aid in hunting these animals.
