Yeah that was definitely a concern. It doesn't seem like spending a feat for 3 languages and +3 damage to a single encounter power is too broken to me. However, it definitely is one to keep an eye on, especially as it'll start out as a +6 bonus for most characters. For a dragonmark with no other combat benefits, I thought it might be okay, but if one of my players takes the theme I'll have to see how it plays.

Great comment! You actually added something very useful about the subject, I hope you will comment the original blog I had linked too! :)

I'm pretty sure the little fellow didn't have a next of kin.
