Anyone on here good with fantasy sounding names?

I need names for a few characters in a fantasy setting. They are human twin boys, but are not identical. They are both tall with auburn hair and eyes that can change from blue to green and all the colours in between, but that's the only similarities.

The first is taller, athletic and is training to be a warrior for the Queen of their country.

The other is a little shorter, nerdy, heavy-set and is learning magic.

The setting is a medieval kind of world with castles, armies and all kinds of supernatural creatures. One of the main characters is half human, half elf, and a lot of characters can use magic, have powers or are not human.

Any suggestions welcomed, even if you have to make them up. :)
