There are several occasions throughout Middle-Earth where you come across runes written on items. Tolkien created a system of runes based upon the Elder Futhark language first appearing in Sweden around 200 AD, although altered them for his works for the dwarvish language.
Elder Futhark was the first written language of the Scandinavia area, in which each symbol represented an idea rather than a sound in itself. Putting the runes together offers an expression of a particular communication.
What runic symbols have you found throughout the Lotro Middle-Earth? Any in particular that were suggestive and meaningful? I'll start this thread with the following image of the rez circle. The first and final runes are Tolkien, but the center two certainly are appropriate based upon the Elder Futhark alphabet:
2. Uruz (strength/determination)
3. Hagalaz (pain/suffering)
