A fork of Rural Dictionary
Someone incarnated with many spirits, especially if they're from their past-lives.
(NOTE: There are many types of multi- incarnates depending on how many incarnated souls they have: uni-incarnate, bi-incarnate, tri-incarnate, quad-incarnate, etc.)
(e.g: 'The oracle proclaimed, 'I am a multi-incarnate of a goddess, demigod and priestess-making me thrice as divine.')
