D&D 5e (2014) / The Forging of the Halfhammer - Part 2 / Otsuka RPG Day

"The Bones of the Mountains nursed in The Heart of Fire, Shaped by the Soul and quenched in the Lifeblood of Ice."
An approximate translated summary on how to work Adamantine - Unknown

The Legend of Heim Halfhammer is a story told to all Dwarven bairns. How in a time of great need he succeeded in forging the Halfhammer that gave him his name and fought back against a hundred thousand Orcneas. He then founded the great Dwarven city of Heim Rada which bears his name. In this story they are taught lessons of dedication and perseverance in the face of adversity.

But Heim Halfhammer was not alone. Indeed, without the support of his Clan, he never would have been able to achieve his great deeds. Having secured the Bones of the Mountain by defeating the spirit of the mountain itself, they next set aim for the Heart of Fire. A living flame that could burn the world to be channelled into the fires of creation.
