THE OLD STORYTELLER
For whatever reason, voicing a gentile old storyteller seems to come very naturally to me. I found that I could do a pretty good Santa a few years ago - sap the jolly old man in red of joyfulness and you're left with an epic old guy who could gather you and your mates around an open fire and read you to sleep... in a good way!
Typically he gets called up to voice trailers for fantasy games set in times past or distant worlds. Naturally, he can be cheery and optimistic, or melancholic and dark; or indeed somewhere in between. Your call of course!
