When she was a small child, Siladhiel's parents were killed in an orcish raid on a small elven settlement near the edge of the woods. She survived solely because her mother hid her from the followers of Gruumesh, and the next day paladins of Corellon found her. They returned her to their temple, where she was raised by clergy, paladins, and avengers alike.

Siladhiel proved herself an apt pupil, joining the clergy at a young age even though the path of both paladin and avenger were also offered to her. With no interest in violence or revenge, she instead became one of the church's most talented healers and known for her patience and level head under pressure. Once she reached her first century, the church began using her as both an emissary between the wood elven cities in their home forest and the outside world, but also as a representative of Corellon's clergy.

Siladhiel has won herself many friends on her travels and though she has seen evil face to face on many occasions, remains optimistic about the world and the people in it. As a priestess of Corellon, she recognizes that often the only way to counter evil is with violence, though she looks upon the use of force as a necessary evil and is careful that she does not become what she fights against.

Sil is a respected member of Corellon's clergy, and has politely refused the position of Head Priestess at the temple in Myth Drannor numerous times. She has a great deal of influence, though she uses it primarily to guide the more militant branches of the Protector's faithful down a gentler path. Siladhiel is a confusing contradiction to most of the novitiates at the temple, advocating a life of peace even as she departs on adventure after adventure.

The care and safekeeping of several holy relics has shortened Sil's lifespan considerably, each one sending divine magic burning through her body. It is enough to take centuries off her life, but by the same token has granted her a wisdom that usually comes with age. Siladhiel has accepted this with as much grace as she can manage, doubly committed to her duties now that she's aware just how little time she has left (from an elven perspective). However, she has no intention of ceasing her wide travels and other escapades any time soon.
