The Runesmith

Blessed by the Gods of the Deep people, the Runesmiths are born with the Dwarven rune for magic inscribed upon their forehead at birth Whilst not impossible for it to be otherwise this blessing nearly always occurs to Dwarves and is part of their ancient Traditions. By this blessing these Dwarves gain the ability to cast magic as an innate baility. By age 5 they have been inducted into the Thunderhammer Clan and in the ancestral halls of the Thunderhammer freehold learn the Sorcerous arts. Over thwe long years the Dwarve shave learned to harness this magical energy and Inscribe it into ancient runes before unleashing their power with great strength when the time comes to release it.

it is not uncommon to hear the ringing of a hammer on an anvil as Dwarven armies march into batle as their Runelords begin using ancient and empowered foci known as Rune Forges to unleash their powers at greatly amplified effect annd casting power or for a party of warriors to have the Dwarven Rune of shield inscribed on their armour as a last resort if things end up failing.
