Jervis Johnson
Games Workshop Employee. Absolutely mutha fucking awesome.
He rides around standing on top of a thunderhawk wearing power armour and playing a guitar.
His skill at writing rules and fluff are so great that they have shattered the boundaries of reality allowing him to write rules that actually affect real life (he has made himself WS BS Attack Initiative Leadership Strength and Toughness 10).
He only allows Matt Ward to continue existing because it amuses him.
Wrote a tonne of the specialist games. Has a column in White Dwarf. Seems to be kept in a basement and fed gruel thats what They think he has in fact given himself a holograph rule so GW wont keep bothering him with questions like "what rules should we give this?"are we doing this right?" and "why are you so awesome?" while he's on one of his global thunderhawk tours righting wrongs and being cool.
He is one of The Four Gods of GW
Actually a lovely bloke who's been treated pretty shabbily by Games Workshop, probably because he sounds like an under appreciated butler character in a P.G. Wodehouse novel.
He and Phil Kelly seem to be the only GW employees that actually like the Eldar. And they are the most competent ones. Make of that what you will.
