When the First Men came to
Eretejva, they brought with them their gods and their understanding of the world. As such, when they chanced upon the ancient creatures, they gave them a name they knew. The old ones call them the Landvættir, the Land Wights of Eretejva, the Spirits of the land.
It is said that the weal of the land and those who dwell within it depends on the might and the happiness of the land-wights; if they are frightened or angered, the land will not thrive and the
humans who live upon it will fare ill in all things. They control the safety and fertility of Eretejva, offering blessings of prosperity. Blessings, that could very well become a curse.
Thus the friendship of a land wight is a useful thing to have; it brought prosperity and luck, even those which would seem to fall outside of these wight's normal realms of nature and fruitfulness of the earth. It is said that they could even whisper murmurs of what is to come and the best time to take action.
For Eretejva, the Landvættir are the Mountain Giant of the North, the Griffen of the East, the Bear of the South, and the Dragon of the West.
It is said that to meet with the Landvættir, that one must find a boulder or go to a waterfall or the peak of a hill. There they must take some food and drink; hallow it to them, partaking in the meal and leaving some; then tell the Landvættir who you are and what you want.
Extreme caution is advised, remember that politeness is the most important thing in dealing with such wights; they are not like the demons of ceremonial magic and ritual, who can (and must!) be dominated and harshly commanded in specific detail, but rather the Landvættir are free beings who have no reason to wish you ill – or even to deny their help to you – unless you manage to personally offend them…As the Lord of the First Men at the village of
Vesturfjord did.
