Downfall of Castle and Country

Downfall of Castle and Country is a mind-controlling World Item.

Description
A World Item that once belonged to the fabled Six Great Gods of the Slane Theocracy. After their passing, the artifact was later passed down to different users of it throughout the ages. Currently, the ownership of this sacred treasure is left under Kaire's control. It was supposed to be used in controlling the Catastrophe Dragon Lord which the Black Scripture was tasked to do.

However, it was instead used in a botched-attempt to mind-control Shalltear Bloodfallen who they confronted to very powerful. The magic of the World Item activated successfully, however the user was killed rendering the mind-control incomplete. According to the Captain of the Black Scripture, although the dress was damaged in battle, it still happens to be usable.

Appearance
The item resembles a qipao, a type of body-hugging one-piece Chinese dress. It has the color of silvery white, with the image of a five-clawed dragon soaring to the skies stitched in gold thread.

Abilities
This dress allows the user to subjugate the mind of any creature, even those that completely possess racial immunity to mind-control like an undead being. While an impressive artifact, it's mentioned by the Six Cardinals to have flaws. One being a limit on the number of times it can be used to charm a target. According to the Six Cardinals, it doesn't seem to work on the Platinum Dragon Lord, a user of Wild Magic.

On the other hand, once the mind-controlled target is resurrected after dying, it seems they're finally free from the item's control. Moreover, a part of the target's memories would also be wiped out from their mind implies to be either the fault of resurrection or this world item itself. In particular, the memories of its target, dating back to their encounter with the user of "Downfall of Castle and Country" were erase.
