Best quotes to summarize each legion?

Each first founding legion seems to have a quote or saying that describes them really well, not necessarily their battlecry but a quote from them nonetheless. Here's what I got so far:

• Word Bearers - "Speak the truth, even if your voice shakes"
• Space Wolves - "There are no wolves on Fenris"
• Thousand Sons - "The only good is knowledge, the only evil is ignorance"
• Iron Warriors - "Iron within, iron without"
• Dark Angels - "Loyalty is it's own reward"
• Salamanders - "Protect the weak, no matter who it is!"

You guys have any quotes that fit better, or work for the other legions?

Edit:

• Night Lords - "We have come for you"
• White Scars - "Laugh while you are killing"
• Emperor's Children - "Perfection is not a state of being, it is a state of striving"
• Alpha Legion - "But this, too, may be a lie"
• Imperial Fists - "Never Compromise. Not even in the face of Armageddon"
