Thank you for pointing this out, Willess! there may have been several iterations in that case. Vorahk being absent from the BE explains why his pronounciation was changed and no longer matches the BEU, because it was made anew.
Apparently I noted own Macku and Nuhvok wrong; they should be MAH-koo for all three and NOO-vahk for the BEU as well. It is a possibility that Pahrak, Kohrak and Lehvak are simply something my friend missed. I also missed adding Kohrak, Bohrok and Gahlok to the list above, but have done so now.
There is also one other difference we noticed between the versions, being that ver1 has Pahrak Va's image replaced by a Lehvak Va.
