[K Peculier]

If you're limiting these instances to a private event rather than sitting in the middle of Cellsvich as Casper the friendly ghost I don't see any issue and give you my approval.

In fact I wouldn't even ever appear in public at all with all this if you want to be taken seriously.

Also I know its common sense (yet somehow not amazingly) but please agree to not shove the spirit into a [insert race here] as a way to get a second life without any consequences.

Whatever player character that accepts to have this character attached to also cannot simply 'give' you their life to achieve the above.
