Wreath Puzzle

Intro
A mysterious artefact comprised of at least three pieces, one of which was found by Ignatious in a ruined Temple of Typhe. It appears to be some manner of puzzle.

Description
The item resembles a wreath in shape and design. It is silver in colour and a little tarnished but less than would be expected, likely due to some kind of preservation enchantment, the traces of which are still active.

It is round but the outer edge has notches that seem as though they fit into another, larger piece, while a smaller piece seems to be missing from the inside.
