A sylvari with a very straightforward and unyielding personality, Arwn is known for her protective streak and her loyalty towards her beliefs. She will fight literally anyone or anything to defend those she is close to.

She is quick to take the roll of offense upon herself, driven by an underlying fear of being unable to save others due to her own inability; while this makes her a strong offensive power it also gets her into a lot of trouble.

Arwn heard the call of her Wyld Hunt while still a sapling and despite warnings to not leave the grove alone she went out as often as she could, hunting down any shred of a lead she could find towards her new found goal. Before long she found herself following the lead of a human who's goals aligned with her own.  
 

As the Vigil was formed Arwn and her mentor joined, the work allowing them both to follow different avenues of research previously unavailable. Along with her research, she took her role in the Vigil very seriously, quickly earning a reputation for herself and her minions as ‘Arwn The Army’. With her focus and ability it left her on a fast track to becoming one of the first Warmasters of the Vigil. With the mantle of Warmaster, she was allowed more freedoms that she used to further her research. She spent a significant amount of time at the Priory, working with Archon Pydre on multiple occasions.

As the Risen attacks became more and more unmanageable, she set aside her research to focus on the battles ahead, from the loss and reclaiming of Claw Island to a place in the newly formed Hopes Legacy on The Humble in the attack against Zhaitan.
Once the dragon was dead and everything calmed down; Arwn dove headfirst back into her research. Throughout Scarlets attack on Lions Arch Arwn was considered MIA, lost through a portal in the mists for not the first or last time. She returned in time for Talæesyn to be promoted to Commander.
