We all know that the writers made this up this season. They always do a lot of things on a season by season basis.

Under a technical sense, the Guardian is just a special light mage.

We got three classes of light mages:

Natural Light mage—Their magic easily get corrupted by the darkness in their heart. See every dark mage.

Savior-Their magic stays light regardless and as a response to a great evil.

Guardian—They absorb dark magic and cannot be corrupted easily lest they lose their magic.

So, technically, there could be a Guardian from FTL and the old worlds but there are a whole lot of dark mages and a lot of mages in general. Rumple probably knows a bunch of them.

It’s just a convenient thing for the storytelling.
