To add to this, I noticed a number of other issues with your post, Enlightened.
For one, how do you know the extent of Yggdri's capabilities? Even if we assume each character has a dossier on the others, what makes you think that she would instantly be able to make a tidal wave of sand big enough to eliminate or at least incapacitate an entire squad? (Just to highlight the fact that you think I can wipe out an entire squad *click* just like that? How crazy powerful do you think Yggdri is?)
Secondly, how close do you think the two crashed gliders are that you can just shout to Squad 1? We aren't even joined together yet, are we?
