Runestone Blessings

In the Isle of Fury adventure, our characters have found several runestones detailing the mythological history of the Norse people. Each stone, when read, has a different magical effect. All effects can be triggered as a free action and can be used once. The players have proven, however, that rereading the stone recharges the effect.

The following text is from Goodman Games The Adventure Begins, from their Dungeon Crawl Classics line.

The Rune Stone of Creation: Upon the rune stone of creation the past is revealed, the true story of the beginning of existence. The planting of Yggdrasil, the world-tree, is described and upon its branches are placed Asgard (the realm of the gods), Niflheim (the underground realm of the vulgar humanoid and the dead), Jotunheim (land of the giants), Svartálfaheim (home of the dark elf), Álfheim (home of the light elf), and Midgard (home to man). The carvings tell how the world was created, and how the years are numbered. The secret origins of the dwarfs are revealed, as is the creation of the first man and woman.

Reading the stone grants the effect of the Cleric power Bless, detailed here in the D&D Compendium:

Bless, Cleric level 2 power

Rune Stone of Fury: Upon the rune stone of strength is carved the secrets of the berserker: the rage brought on by battle, a gift from Thor, the ultimate weapon of Northmen, of Æsir and Vanir against their many foes. The runes recall the events that led to the first war, what occurred in the struggle between the Æsir and
Vanir, and the peace that was wrought from the bloody conflict.

Rune Stone of Wisdom: This rune stone reveals what Odin sacrificed of himself in the pursuit of knowledge. The stone speaks of Odin’s eye, which was plucked out in exchange for inner sight. It tells the story of how Odin willingly impaled himself upon his own spear and was hung from the branches of Yggdrasil until he saw the secret of the original rune stones. The stone reveals that only through pain and loss was knowledge gained.

Reading the stone grants the effect of the Paladin power One Heart, One Mind, detailed in the D&D Compendium:

Rune Stone of Rebirth: The rune stone of rebirth reveals a story of hope. It speaks of the day when a sliver of golden light will shatter the endless gloom of night. Out from the ashes of the destruction of the gods, a beautiful world will rise. The breath of life will once again fill the lungs of the fair Baldr. Baldr reborn will travel the new world and everywhere his foot touches ground, abundance will sprout without the sowing of seeds.
