Yggrasil is the tree of the cosmos that holds the nine worlds in Norse Mythology. Midgard (Middle Earth) is the realm of the humans, which is protected by Thor.
I used the Younger Futhark (Scandinavian Futhark) of the scandinavian Norsemen (Vikings). It has been used between the 9th and the 11th century. These are the Runes of Old Norse. The Elder Futhark is Proto-Norse and was used before the Viking age (8th century). Most of the runestone inscriptions contain Younger Futhark Runes.
The Runes on the bottom are from the Fyrby Runestone (Sö 56) Södermanland, Sweden.
