According to your previous answers, Long-whiskers the Cartographer was Lucien's Senior Artisan. Your Mentor is a different mouse. In Lucien's case, it was very likely his father.<br/><br/>Lucien's belief is huge and ambiguous. In terms of Mouseguard, "I am the shield that guards the realms of mice." works perfectly. It's concise; it stirs the mind to read it. It gives you the face of Lucien's persona just by reading it alone.<br/><br/>Your goal is also a bit too grand in scope. Remember you have four other mice with you, and you all have the same mission. Go with one of the three, and leave the other two for others.<br/><br/>Your instinct is right on, and a good example for others to follow.
