"Demon Blood..."
The bloodlines that the wizards refined were all from the Abyss Species.
The Bottomless Abyss is also a hunting ground that wizards fancy, though they don't delve too deep, playing around on the surface with hunting activities and resource gathering.
Basic safety is still guaranteed.
Unlike the universe, the Bottomless Abyss exists in another space, much like the Inverted World, as the ultimate aggregation of malice from all spirits and creatures.
A new layer of the Abyss forms every day.
The various strange Abyss Demons are the native creatures inside.
It's just that their birthplace is so bizarre that they are inherently part of the chaotic and evil camp.
They are far more powerful and much more insane than the Evil Energy Demons created by the Dark Titans, like Western-made goods.
Padolon has been invaded by the abyss before.
