Eitri and a dwarf placing satchel charges in the snow.
Eitri is a dwarven demolitionist who served in the Second War against Soulblighter, taking part in the expedition in the Stair of Grief to find the Deceiver. While scouting in the snow, berserks spotted terrifying shapes lurking about within the dense weather, which turn out to be the Mauls and the undead. Eitri and his team of dwarven demolitionist then prepared ambush sites throughout the pass to fend off the Dark, giving Twelve Motion Jeweled Skull time to dig up the Deceiver's Scepter.
