This is the Norse alphabet, known as Futhark (named after the first 6 letters of the Norse alphabet).
"A", "E", "N", "S" and "T" represent the compound letters, otherwise, NO CAPS REQUIRED! There's also numbers & a symbol for the SPACE.

Playing around with octagonal shapes. One child of this phase was "Zapotek", which Xenophilius mentioned completely right. Another one, beside some others , is this one. Somewhere in the back of my head this is inspired by the wonderful "fs Kronos" by will.i.ૐ. Not so much in it's look, but in it's heroic, oldfashioned feel. The feel it's purpose is decorating an epic fantasy novel :) I hope the upcoming sample can make this clearer. Enjoy
