from Asche, however I can comment on this one since you technically already know the answer:
>When / Why was it given to Ariel, if the most recent Warden still needed it?As a sort of plot point, the bracelet has never been referred to as a "family heirloom". You know that Artemis presented it to the Founder due to Dryad's Atelier, but it essentially vanished from history after that. The next mention of it was when Ariel came into possession of it. It is safe to assume it was never involved in Dryad's pacification, or the Valen family in general, beyond the Founder's initial possession of it up until the point Ariel reacquired it.
>"Well how did Ariel get it, then?"This is a more pertinent question to pose. As far as you know, she just found it, and as far as you can remember, it was never treated with any particular sort of importance or reverence befitting a Relic. Until sometime past the quest's starting point, you only ever knew it as a memento of your now dead sister, after all.
