Fornlang is a longsword of delicate elven craftsmanship - with its elvish name roughly translating to Blade of the North, it was bestowed upon the first king of the snow elves and since then has been passed down through several elvene generations, serving as a royal symbol and as a weapon to guard this frozen realm. The sword's hilt is made of mithril with a large sapphire inlaid in the pommel and its blade is made of pure crystalline ice, carved from the very origin of the glacier covering the Great Mountain, the central landmark of the snow-elven realm.

Sentience. Fornlang is a sentient neutral good weapon with an Intelligence of 14, a Wisdom of 12, and a Charisma of 16. It has hearing and darkvision out to a range of 120 feet. The weapon communicates by transmitting emotions, sending a tingling sensation through the wielder's hand when it wants to communicate something it has sensed. It can communicate more explicitly, through visions or dreams, when the wielder is either in a trance or asleep.

Personality. Fornlang seeks the advancement of elvenkind and snow-elven ideals,  Courage, loyalty, beauty, music, and life are all part of this purpose; and wants to guard the snow-elven realm, unleashing winter's wrath upon those who are intruders from outside, break the law or otherwise pose danger to the realm. Once the sword has bonded to an owner who shares its ideals and cares for the realm of the snow elves as the sword does, its loyality is absolute, it will serve its wielder no matter what. if the sword has a flaw, it is overconfidence and judging others too harshly.

Dormant. The longsword grants you the following properties while in its dormant state:

• The sword has the finesse property.
• You gain a +1 bonus to attack and damage rolls made with this magic weapon.
• When you hit with an attack with Fornlang, the attack deals an additional 1d8 cold damage.
• Freezing Strike: As a bonus action, you can cause the sword's blade to flare with intense cold for one minute or until you hit a creature with an attack using this weapon. That creature must make a DC 15 Constitution saving throw or be frozen solid for 1 minute or until someone uses an action to break the ice. While frozen, a creature is restrained. You can use this ability a number of times equal to your proficiency bonus and regain all uses when you finish a long rest.

• You gain a +2 bonus to attack and damage rolls made with this magic weapon.
• The additional cold damage increases to 2d8.
• You gain resistance to cold damage.
• The saving throw DC for the sword's Freezing Strike increases to 18.
• Snow Magic: While you are holding the sword, you can cast one of the following spells (saving throw DC 18) either as an action or, when you take the attack action on your turn, in place of one of your attacks: cone of cold, ice storm, sleet storm, slow or wall of ice. Once a spell has been cast using the sword, that spell can't be cast from the sword again until the next dawn.

• You gain a +3 bonus to attack and damage rolls made with this magic weapon.
• The additional cold damage increases to 3d8.
• You gain immunity to cold damage and resistance to fire damage.
• The saving throw DC for the sword's Freezing Strike and Snow Magic increases to 21.
• Blizzard Aura: While you are holding the sword, you radiate a blizzard-like aura of intense frost, strong gusts of wind and heavy snowfall. The area within 15 feet of you is lightly obscured and counts as difficult terrain for your enemies. In addition, each creature of your choice that starts its turn within 15 feet of you must make a DC 21 Constitution saving throw, taking 3d8 cold damage on a failure or half as much on a success.

Random Properties. Fornlang in its dormant state has one minor beneficial property and one minor detrimental property. When the sword attains an awakened state, it gains an additional minor beneficial property and an additional minor detrimental property. When the sword raches its exalted state, it gains a major beneficial property.

Destroying the Sword. Only a direct descendant of the royal line of the snow elves attuned to Fornlang can destroy the sword. To do so, the sword must be brought deep into the glacier caves at the summit of the Great Mountain - and there, at the very origin of the Great Mountain's glaciers, a ritual must be performed, which will take several hours to one day. Once the ritual is completed, the sword's blade is reunited with the glacier's ancient ice and the hilt can be molten down in a mithril forge.

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