Eidolon is the name of the summoned guardian/familiar of the Summoner class. I will admit, I've never played the Pathfinder videogame even though I've played the tabletop game a lot so my knowledge of the game might be a little skewed. I've also never played with mythic paths but I'll do the research necessary to stay on top of it.

An example of a Myth Path is "Archmage" or something like "Angel" "Devil" "Demon" etcetera.
