Alaric, the Sun Sword

I am Alaric, Sword of Morning, Hand of the Grave King, forged in the fires of Kalumvir when the world was young. I was the radiant hand of Sir Ogier the Red and was the bane of the First Gorgon. I was wielded by the Lady Vanya Al-'Adl in the Battle for the Burning Sea, and was crushed under the heel of Khalussir the Resplendent. I have witnessed the long ages of the world, and have seen many defeats, and many fruitless victories.

This item appears to be the enameled hilt of a broadsword. Inscribed in ancient elvish runes, which are magically legible to any creature with 5 intelligence or higher, are the words: I AM ALARIC, SPIRIT OF THE DAWN. MAY YOU BRING REST TO THE RESTLESS.

While grasping the hilt, the weapon's chosen wielder can use a bonus action to cause a blade of pure radiance to spring from the hilt, or make the blade disappear. While the blade exists, this magic longsword has the finesse property. If you are proficient with shortswords or longswords, you are proficient with this weapon.

You gain a +2 bonus to attack and damage rolls made with this weapon, which deals radiant damage instead of slashing damage. When you hit an undead with it, that target takes an extra 1d8 radiant damage.

The sword's luminous blade emits bright light in a 15-foot radius and dim light for an additional 15 feet. The light is sunlight. While the blade persists, you can use an action to expand or reduce its radius of bright and dim light by 5 feet each, to a maximum of 30 feet each or a minimum of 10 feet each.

Sentience. Alaric is a sentient lawful good weapon with an Intelligence of 11, a Wisdom of 14, and a Charisma of 19. It has hearing and darkvision out to a range of 120 feet. Alaric communicates by transmitting emotions to the creature carrying it or wielding it. It is singularly loyal to the ancient law of the Lord of the End of All Things, and its purpose is to destroy the undead and ensure mortal adherence to the Universal Principle.

Proficiency with a Longsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
