Always smiling and always curious, Sister Aliana Farwalker, elven priestess of Sirilius, has a love of books and knowledge, but a fear of the outside world.
Her large blue eyes always twinkle with merriment, and her long blonde hair seems to always flutter in the breeze.   Though her prominent holy symbol shows her to be a cleric, it's obvious she's had intense combat training, both in the weapons of her faith, and her race.
She always has a bow, plus the longsword common to her church's warriors.
Her armor and weapons are always very polished and cared for, and she's always picking up random souveniers for wherever she goes, stuffing them in various pouches and pockets.
She has a varacious appetite for stories and songs from around the world, wanting to hear everything.

Left as an infant on the temple steps of the Sirilius Temple, the elf girl was raised by the mostly human churchfolk, becoming a sort of mascot as she matured over the next couple of human generations.
Feeling that her mysterious arrival might suggest some kind of danger, the girl was taught to keep a very low profile, nearly to keep in hiding, for decades, until it became second nature.   Aliana spent her time reading and studying as she grew up.    She was very content to do so without complaint for decades.
When the last grandchild of her last childhood playmate died of old age, though, Aliana began feeling like she'd been in hiding too long and began to feel a strange wanderlust.  The outside world was scary, though, so she resisted the call of adventure until some humans made her feel guilty.  Gathering her courage and stocking up on supplies, the elven acolyte left the shelter of the temple, heading north in search of adventure.
