Frostmourne

What it's about
Ruins of fallen kingdoms appear in your world: the castle of Nordholm, the Kings' Crypt, a necropolis, temples of Light and Sun, and the Void Citadel. Villagers, spirits and the undead tell how King Artos fell and where his sword came from.

At the centre is the Frostmourne sword with 8 abilities on dedicated keys: Frost Nova, Soul Reap, Death Grip, an Army of the Dead, Frost Leap and more. It comes with a skill tree and a cooldown HUD.

Bosses
Lich King Artos. Master of the sword and the throne. A three-phase fight with ice rings, a soul beam, risen dead and cursed circles. He talks to you first, and the conversation changes if you've read The Legend of Artos.
Velkar, the Emerald Necromancer. Hovers over an open tome and commands bone acolytes, plague ghouls and a colossus. Fights with green fire and spells.
The Blood Duke. A vampire aristocrat who sleeps wrapped in his wings. Summon him at night with the Blood Seal. His fight is built to be beautiful: a waltz of spectral blades, a masquerade of shadow clones, a fountain of blood, strings of blood, a cyclone of bats, and an eclipse finale. He has his own soundtrack and boss bar, and drops 3D weapons and trinkets.
The Death Knight. A horned warrior in runic armor, which you can earn and wear.
