Sword of Kings and Queens

Weapon (longsword), legendary (requires attunement)

This jewel encrusted longsword is made of a purplish metal engraved with twin crowns. You gain a +2 bonus to attack and damage rolls with it.

It contains the souls of both a demon and an angel. It is neutrally aligned.

Powers. The sword has the following abilities:

• The sword can emit a blinding flash once per day, recharging at dawn. Creatures other than you within 30 ft. that can see must make a DC 16 Constitution saving throw or be blinded for 2d4 rounds.
• Once per day, it can steal the dreams of a sleeping creature. It learns what has happened to the creature during the prior day and what its primary goals are.
• It can cast locate object once per week. It will only use this power to locate the Sword of Princes and Princesses until found, and will then allow you to use this power to seek other objects.

Sentience. The sword has an Intelligence of 13, a Wisdom of 15, and a Charisma of 16. It communicates telepathically with a commanding voice.

Curse. This curse can only be removed by a wish or by the sword’s destruction. The curse attracts monsters to you and creates hostility between good and evil (though not neutral) creatures and you.

Destruction. Magic runes inscribed on the blade read “destroy me”. They can be understood with comprehend languages or a DC 20 Intelligence (Arcana) check. The sword can only be destroyed by melting it in lava. If destroyed, this action frees both the demon and angel from the sword. Both then disappear. This lifts the curse (but not the geas) from the sword. Better yet, the sword then reappears in your possession (in an un-cursed state) the first time you are unarmed, disarmed, or in danger or combat and without a weapon. You will not know of this last effect until it happens. Further, the sword gains the ability to cast the commune spell once per week.

Geas. The geas on this sword forces you to quest for what it considers its offspring, the Sword of Princes and Princesses. If you take a long rest having not actively sought the Sword of Princes and Princesses since the prior long rest, you take 5d10 psychic damage. Finding the Sword of Princes and Princesses is the only way to remove the geas.
