So far I have 17 characters, did I miss any? Main Character, Eylia, Zackon, Zoura, Eryndar, Krystelle, Ituri, Rakear, Unala, Ashaka, Atayu, Eodai, Taiyleu, Zulock, Ria, Therris, Aburos. Gotta catch'em all!
Woah, just found a huge bug. Once you get the first "small hourglass", you can go to the Key Items Section, select and use it over and over, not only gaining EXP but also "Eryndar Quest 4 Scrolls", ALL of which you can use after you beat the evil in the crystal. Even with this bug and the missing "crack on the wall", I am enjoying this game very much!
"Exploring" stages do not have a cooldown and you can accelerate their exploration time by upgrading units and massing them on the stage. "Fighting" stages can also be accelerated by upgrading units and massing them on the stage BUT they have a cooldown AND you lose units therefore reducing the speed of completion. As far as I can see, "Exploring" stages make a lot more money in the long run even with the lower instance payout.
