Niniane's Wand

Niniane O'Faolain, more commonly known as the Lady of the Lake, was a powerful witch that lived during the 5th and 6th century. The exact time and location of her birth and death are unknown.
Niniane was known to be an incredibly beautiful woman who apparently lived unusually long, possibly due to her blood being not entirely human. Today she is mostly known for being one of the closest friends and advisors to Myrrdin Wynn Emrys, more commonly known as Merlin.
Niniane had always had a special connection with water. She was able to communicate with its spirit, similar to what a Visvalker may be capable of, although this is attributed more to her likely possessing non-human blood. Because of this, she was exectional at using water- and ice-based spells. After she moved to live at the shores of a lake, she often spent time meditating in a shrine on a small island at the lake's center. It was said that she could see into the lake's depths and receive visions from its spirit. Some accounts claim that she was even able to control the movements of the lakes' water through her magic. This deep connection with water, and the lake in particular, was what earned her the moniker "Lady of the Lake".
Her wand reflected this. Although it is not known which materials it was crafted from, it was said to have had a grip of black wood and silver, with a shaft seemingly shaped from ice.

This is part of my Powers Within worldbuilding and story project. The wand's design is heavily inspired by Jadis' Wand from Chronicles of Narnia. The design just fit pretty much exactly what I had in mind.
