You said that you made up some Ideals for the Stonewards? I'd love to hear them! I may or may not be writing a fusion fic which has another character becoming a Stoneward, but the Ideals themselves I never could think of outside of the second Ideal being the entire Order's purpose of "I'll be there when I'm needed."
What a fantastic question!
These are the ideals I personally wrote up and hold.
Stoneward virtues are as follows: strength, resolve, dependability. To stand strong in the face of adversity and challenge, to not bend and break but to push through and persevere until the bitter end. To always be reliable, like a good shield brother in a phalanx, one must be able to trust your brother, as he is protecting you while you protect your other brother.
Life before death, strength before weakness, journey before destination. (Obviously.)
I will be there when I am needed. (This is the core tenet of the order, equivalent to the Windrunners "I will protect those who cannot protect themselves". Most who join the order will swear this ideal as it is the most basic beyond the first.)
I will stand where others fall. (This is the tougher one. Requiring not simply strength of its members, but rather ignoring the option of failure entirely. Stonewards are known for their stubbornness and here is the place where that stubbornness is required. This is the ideal that Taln would have clung to while 3000 years deep on damnation. This is the ideal that will plant your feet upon the stone, nay, within the stone, and make you immoveable.)
I will accept that there are times I cannot help. (Perhaps the hardest ideal to swear, many do not reach this ideal. While on the surface, it may seem to clash with the previous ideal, the previous is based on the choice to never choose selfishly, this is to accept that circumstances and situations will sometimes force you into choosing one person to help over another with no possibility for both. Stonewards, especially during wartime, have a habit of pushing themselves too hard, going too far, running themselves into the ground attempting to be there for everyone. Whether that is on the battlefield, watching a brothers back, or emotionally as they comfort those who have lost loved ones. However, they are still only human, and sometimes must choose between helping one over another, or taking rest when others still are in need in order to help later. Admitting that even their immense resilience is not limitless is soul rending and must be understood to proceed.)
I will allow another to sacrifice themselves in my stead. (The paramount. The most difficult, yet most important ideal to understand and internalize. Whether it is physically in battle, emotionally in a relationship, or socially in a party, Stonewards are givers. Willing to sacrifice all they are for those around them, often the hardest thing is to allow another to do the same for them. There is a throwaway note in RoW from a stoneward that mentions that he spent his whole life looking for a way to give it up for someone else, but worries "that that is the easy way out". To live, and live well after having a loved one sacrifice themselves for you is the hardest thing a servant can do. To not feel guilt for the discomfort of another, even if it is chosen in order to give them comfort.)
