What's the story behind your SN?
Well - Warder is obvious to anyone who's read WoT. In the martial arts group I'm part of I'm the one who's rather known for keeping his armor cleaned and polished so "silver" is simply the proper colour of my armor.
Thus - a warrior in silver armor with a penchant for defending ladies - SilverWarder.
As to meaning - I believe in defending those who cannot defend themselves. Therefore Warder seemed appropriate although Aes Sedai are hardly defenseless.
