Thanks for the welcome and the White Dwarf issue.william King was called Bill King in those magazines, you may have some luck using bill king in your search, although those are the same people.
Here's what i can find, i don't have alot of white dwarfs from back then.
eltharion's backgroundstory is in 158...
but if you have the armybooks from that year, Grom's armybook has 2 pages of fluff which leads up unto his fleet leaving for the elf lands, then Eltharion's fluff in the stinky pointy-ear book... i mean, the high elf book, has 6 pages about Grom's final hours. that might be the story written by Bill King, as he is one of the writers of the armybook.
wow... i had a fire once when i lived at my parents... christmas candles.. my fault...On two separate occasions I had my books damaged by water - first when our basement flooded
