more info for you dawgs:

so it's pretty difficult to find anything on this item other than it's initial entry on websites (magelo - 2002, lucy - 2005, alla - 2007) but i did some sort of comparative visual basic gui interface crap to help provide context clues of when it was implemented. using the magelo database (which has the earliest entry for most of the upgraded sky reward items), i looked up all the initial entry dates of all the upgraded items that required a piece off of the sister of spire (island 7). those items/dates are as follow:

thelvorn, blade of light - oct 29, 2001
vemilion sky ring - nov 27, 2001
wu's fist of mastery - dec 16, 2001
amulet of the void - apr 7, 2002
spiroc banisher focus - aug 23, 2002
band of wailing winds - nov 18, 2002
arydryidriyorn - may 19, 2003

as you can see, the amulet of the void lands smack in the middle of the seven upgraded items for their initial entry date on magelo. this would certainly make it seem like it was one of the items implemented with the jul 19, 2000 sky item upgrade patch.

and for comparison's sake of initial entries of the original reward and the upgraded reward:
amulet of planar transference (original reward) - march 10, 2002
amulet of the void (upgraded reward) - apr 7, 2002

it also appears the upgraded version did require a cloudy stone of veeshan to use the effect, the requirement was only removed at a late time when a lot of items stopped requiring regeants to use.

that's about all i can find. hopefully you guys take a look at this and decide it's enough evidence that it should be in the game currently.
