Best Themed Build: Forge of the Frozen King by Erusgizmo

Here’s their story:

Long before the northern kingdoms fell silent beneath the ice, the cavern known as Shiverdeep was the seat of an ancient frost sorcerer-king. From his frozen throne, he commanded terrible winter spirits and forged weapons imbued with the power of the endless cold.  But ancient heroes sealed the cavern, leaving him to freeze in darkness. 
Now the orc clans, driven from their southern homelands by war and famine, have come seeking the lost power buried within the depths. They have relit the ancient forge, awakened the braziers, and begun dark rituals beneath the frozen falls.
