Most of the Narnia books by C S Lewis leave a lot to be desired.
Nothing special really, just simple fantasy for kids.
But the second to last is an absolute banger.
A prequel: The Magician's Nephew.
It's basically Sliders, or Star-gate, same premise.
A couple of kids, jumping between worlds with a pair of magic rings.
One brings you to the forest between worlds, the other allows you to enter other worlds by diving into any of the pools in the endless forest.
The kids happen upon a dying world, and meet the witch queen, who manages to hitch a ride out of her dying world.
Crazy shit happens, and eventually they manage to drag the witch back into the forest, and into another pool, another world, one that's just being created.
But not before she smashes some kid's ribs with a street lamp she pulls out of the fucking ground!
That's why Narnia has a street light, forever lit, in the middle of a forest, it's imbued by the power of creation.
That's why everyone in Narnia is an animal, except the witches who look human, they are outsiders.
That's why Aslan, despite being Narnia's creator, a literal god, seems to have trouble dealing with the witches.
He may be a god, but not their god, not their creator.
The witch is older than Narnia, she was there before it was created.
I draw, code, and make memes sometimes.
