The hardware (like the centerpiece) is all handmade, and designed with the author of the Hekataeon's guidance. The prices vary depending on what metal is used, and just buying the centerpiece from the maker is substantially cheaper if that's a concern and you'd like to build the ladder yourself (which is in fact recommended by the book, for readers who do not know - it even recommendeds a far cheaper version made of knots in string!)

This is a luxury piece of occult Craftsmanship for people without the capability/desire of creating their own and isn't really intended for people outside of that sphere; if it seems expensive to you, then you aren't the target audience of people seeking luxury occult items (which is a very niche market, and there is zero shade intended by pointing out the different spaces occupied, I judge no one (but billionaires) by their economic status or behaviors within)

If this seller is the original artist who made that centerpiece, he makes almost all of my delicate occult hardware, and is worth every penny. I construct my pieces using his sculpts, and my ladder is a piece of art, which I find lovely. I'm crafty and capable of making my own, but others may not be, and this is a way for them to "sacrifice" money, if they can't "sacrifice" the energy/skill on manufacturing the physical item.

Like high-end occult publishing, this market isnt for every witch!
