Zemial's founder Vorskaath, co-wrote half of the His Majesty at the Swamp album as he was the guitarist who went by the stage name, "Necroslaughter". The information is there out there on an online interview to confirm this or you could ask him yourself.
And judging from his personal MySpace profile, I'm not surprised there were elements of outrageousness as I like to call it, incorporated into that album.
The Greeks fucking kill, period. Their brand of black/death metal is my FAVORITE style of metal.
