Well if you look at the facts Ivan is pretty evil so calling something good a "darkness" wouldn't be so surprising. however it is obviously something bright, so I'd say the most likely possibilities are

A: a dragon (I'm rather skeptical about this one)

B: a fairy (it's an even worse theory than the dragon)

C: the buildup of the good times and friendships in the guild (Ivan WOULD call this a darkness, i think, and Mavis definitely a good thing, this is actually pretty likely in my opinion)

D: the One Magic (ok suppose Mavis had managed to preserve the One Magic and hid it under the guild, I wouldn't be surprised if she did and the One Magic WAS supposed to be light)
