It fits, I suppose. Although Wilshapers focus most heavily on freedom. I imagine them away from the front lines, freeing PoWs and liberating those who are taken advantage of during wartime (or anytime). I can see it as "I will stand when others fall" in the fight against oppression, but other then that I think it might fit better in another order.
Edgedancers, maybe. "I will remember" falls closely with "I will stand when others fall" In my opinion. Both relate to doing what others fail to do. Tied together they might form something like "I will remember those who have fallen and stand for those who fought".

Their primary focus is "I will be there when I am needed" and when is someone needed more then when everyone else has fallen? Stonewards are said to put others interests before their own, and are unwilling to bend their oaths for personal gain. On the Orders page Brandon put out it says this about stonewards:
