That's what we call them in Aselia! A friend of mine is a Summoner, so she can make pacts with the Spirits and then Summon them to help us in battle or get us out of a tight spot! When a lot of a certain type of mana gathers together and becomes sentient, it makes the Summon Spirit. So mana and fonons sound kind of similar with how they make Summon Spirits, even if you don't call them that in Auldrant!

Heheh, you don't need to apologize! I only know as much as I do about them because we had to make pacts with all of them and I was traveling with the Professor. I don't think I'd know as much as I do if we didn't need to make pacts with all of them.
