Absolutely there is!
The current round of Legendary Summoners have entire stories as their lore on the website instead of simple descriptions. I really like Yodin's. Check it out!

I'm laying the groundwork for these epic historical events to be written about in the future. Over the coming weeks, I will be implementing full historical timelines. There will be a lot for creators to work with, but I cannot get too deep into a single moment of history when I'm dealing with thousands and thousands of years.

Right now, everything is teasers. Hehe.
