Growing up in an affluent manor, as befits ladies of her stature, Eollayn had the responsibility to learn an instrument. She broke all the rules (and most of the things in her room) by choosing the drums, a technicality her parents never envisioned. Eollayn is quite good at finding any technicality that allows her to have more fun than she should: breaking things is fun, shopping is fun, and she is nothing if not efficient. Surprisingly she did not grow up spoiled, and is quite content in her poorer moments as long as she's enough coin to do whatever happens to strike her fancy. When prevented from constant amusement, however, she turns fierce and dour, breaking friendships as easily as her drum sticks.

Her talents at music seem to only extend to percussion and screaming...this even follows to her weaponry, where she favors baton-like clubs in battle. (Her vigor and aptitude for hitting things with a cudgel becomes quite dark indeed, akin to certain crossbow loving princes we've read of by the hearth.) Whether in battle band or pub band with Eollayn, have faith that you will know it. And though she usually does enjoy being the center of attention, most onlookers are wrong when they make that assumption: as long as she's having fun, and no one is interfering with that fun, she doesn't mind if she's blending into the background. Unfortunately, like any alchemist worth their salt will tell you...some things just don't blend.

She is at heart a hedonist, and considers herself grandmaster of that guild. Deep down Eollayn does know such behavior can be self-destructive, but  the belief of immortality that only comes from youth and a moneyed upbringing. The way she sees it, she might be the candle that ends up burning out twice as quickly...but damned if she doesn't burn four times as bright.

Eollayn usually hangs around Bree, but can be seen causing trouble at The Lumbering Dwarf Woodworks since she's constantly breaking her drums and clubs from her over-exuberance​. Upon hearing that "the little man who gives me things to hit" couldn't afford to build a larger shop, she went on a bit of a money spending splurge not only funding his new location, but pumping coin into the sleepy village of Fullbridge as well as "take a job" as its "Head of the Tourism Board." Why a sleepy village needs a tourism board probably has far more to do with Eollayn being the other kind of bored, and if you've ever caught sight of her promotional flyers and materials, you can see that it's a passionate boredom indeed.
