A translucent leaf-shaped blade made from a single crystal of amber. The hilt is made from bronze, with an ornate circular guard set with a large polished amber sphere. The blade carries an inscription in elvish: nilisnebar - Nilisnebar, 'Storm-Glass (Amber) Blade'. Magic swirls throughout the crystalline blade, and sometimes small jolts of lightning can be seen inside the amber.
Nilisnebar was wielded by Aerilwyn Nilteril, a legendary bladesinger who served the Teccan Empire at its height of power.
Sentience
Aerilwyn's very essence has infused into Nilisnebar, making it sentient. It is Lawful Neutral and has an Intelligence of 22, a Wisdom of 16, and a Charisma of 15. It has darkvision with a range of 60 feet and communicates telepathically with the wielder, preferring to speak Elvish but will speak Common if needed. An attuned creature can respond telepathically.
Personality
Aerilwyn is intelligent, calculating, and hungry for power. She knows much about magic and the history of the Teccan Empire, and will share these facts with wielders she considers worthy of continuing her legacy. A worthy wielder of Nilisnebar, in her view, is someone who is an accomplished arcane caster with ambitions (especially political or pertaining to an organization) and the drive to accomplish them. If the wielder is not worthy, she will try to guide them toward this path.
Aerilwyn enjoys seeing evil destroyed by magic, especially lightning magic. Aerilwyn is still loyal to the Teccan Empire, and is shocked upon hearing of its fall. Her ultimate ambition would be to revive the empire, installing a worthy emperor once again.
