Definitely not. Savageland is a work of imagination. It doesn't draw from actual events or true stories. It's all about creating a fictional world and plot to engage the audience.
Sort of. The core concept of Savageland might have roots in real incidents, but the details and plot have been fictionalized and embellished to make it more engaging for the audience.
I'm not sure specifically as there could be various stories with that name. It might be about a savage or wild land, perhaps a place full of untamed nature, dangerous animals, or a land with a primitive and wild history.
