Heren Istarion has an Italian accent. Yup. Aware he isn't Italian and so this is, at the very least, a little doubtful, but hey. See, I did a scuba diving course this week when I was on holiday, and on the second day he created the heavens and the...sorry, distracted. Ahem, sorry, on the second day, there was a scuba diver who looked so very, very like our dear H-I; so much so that I was actually tempted to sort of subtly mutter 'George' or 'Heren' when I passed him: that is just how convinced I was.
...and the I passed him a regulator and he replied with 'gratsia'. Ah. Not H-I then. But nevertheless, it is the voice H-I has now inherited - and a damn good voice it is as well.
