I'm entertaining a thought about changing the class names to fit a Middle-earth setting. Game mechanics are otherwise unchanged. I'm going to follow the list of MERP classes, but I'm assuming that D&D/OSR will be used.
Fighter is renamed Warrior. Magic-user is renamed Lore Master. Cleric is renamed Healer. Thief is renamed Burglar. Bard is renamed Minstrel. Ranger is renamed Hunter. That way "ranger" can refer to the Rangers of the North or the Rangers of Ithilien.
Not sure if I'll actually do this, except maybe for healer and burglar. Just a passing fancy.
This song is Galadriel's Lament for Eldamar, which appears in Fellowship of the Ring. I heard it was supposed to be part of the LOTRO soundtrack but didn't make it to the final cut. Beautiful piece. Music was composed by Thomas Chance. The singer is Jenny Jordan Frogley. The lyrics are by JRR Tolkien, of course, and you can see them here.
