The knight-commander is wholeheartedly devoted to both the one hailed as the Guardian of the Seal and his silver home of the fae; from his first appearances, he is observed to be regularly undertaking direct orders from the Head Icon King with no hesitation. The power of Silver and the mantle of commander came at a great price: relinquishing not just his unique Cookie flavor and scent but also the memories of his days as an ordinary Faerie Cookie, a trade-off he refuses to elaborate on as seen when he converses with Head Icon Pure Vanilla Cookie. Many of Mercurial Knight Cookie's quotes are both fueled by a deep resolve to maintain the equilibrium of the world via safeguarding the Silver Tree and its Guardian and his own dreams of living in a safer Earthbread one day, in which he resoundingly proclaims that with his entire being, he will go any length to achieve peace for all Cookiekind. He also has a habit of unintentionally scaring Cookies with his silent presence as his wings allow him to move freely without making any sound.
