Grants & Megid

[Dew]

Are there any differences in the grants and megid from the DC version and the ones in the new version? For example...do they look different at higher levels or anything. Also, I keep hearing about Megido...is this just a spelling error or is this a high level megid disk? If so, is there a grants one? Can all the forces use Megido (if it exists) or the Grants one?
Thanks to anyone who answers.
