I had been waiting to see if there was any elaboration on the title doc texts, or an outline of information to be included on it. There hasn't been, so here's my attempt:
WHisper
Guardian's Echo
Awarded this title for being the most silent of the guardians.
Perseverance is with this one, as daily, he would tend to Bob, speak little, but watch much.
This title is the epitome of the root role of a guardian, and further proof that grand deeds are not always required to show ones dedication, deeds such as simply being there are just as important.
