I can't tell you how much I love these developer posts! :D
Okay, so the latest post was about how they are improving characters, you can read it by clicking this link, but what interested me was THIS interesting clue at the end of the post:
Of course, being the good samaritan I am, I decided to try and figure out who "In-" was.
Here's a list of all the heroes beginning with "In-". I'm pretty sure "In-" is a hero, but it could just as easily be a place. Anyway, I went through all the names, except IN-visible Woman (Girl), but I didn't find any likely candidates. Will you? You can see the list here and decide for yourself!
