How do you place numbers into a palace?

Convert each chunk to an image with a number system (e.g. the Major System), then set those images along your loci in order.

A palace stores images in order, so numbers must first become images. Chunk the number, turn each chunk into its peg word or Person-Action-Object, and drop them at successive loci: for 3247… → moon at the door, rake at the hall table, and so on. Walking the route reads the digits back. This pairing — image system + palace — is exactly how competitors memorise hundreds of digits.
