For some reason my mind went to Towns 2. Like, maybe we can have... summons? So we'll get to have Fluffs following our avatars around? e___e
Or maybe they'll be an alchemy thing? I don't think they can have too much to do with a future event, because it would make it difficult for newer/hiatus'd players who aren't here now to participate.
Edit: Hm, looks like it's for an event after all? Hopefully the souls aren't super involved, or else become otherwise obtainable come summertime. I understand the logic behind rewarding those that have been on the site longer with advantages during events, but I don't think it's an idea most of the userbase will take well to. I do hope I'm wrong on that, really, I think it's cool to connect events like this. Guess we'll just have to wait and see! c:
