Looking for a source on these gloves:

[Atenstein-zuljin (Atenstein)]

Heroes’ Dreamwalker Handgrips of the kind that aren’t restricted to druids.

Wowhead doesn’t list any source, yet does list what it disenchants into so it is obtainable, apparently.

Heroes' Dreamwalker Handgrips

[Sniperorc-azgalor (Sniperorc)]

Chasing the link for the full mog set show that it’s T7 from early WotLK:

Heroes Dreamwalker Battlegear (10 Recolor)

This is the Tier 7 set. They are “purchased” with Tokens of the Lost Vanquisher by Valerie Langrom in Dalaran.

Naxxramas

Head: Kel’Thuzad
Legs: Gluth and Thaddius
Shoulders: Gluth and Loatheb
Chest: Gluth and the Four Horsemen Chest

The Obsidian Sanctum

Hands: Sartharion

The Tier 7 set items also drop directly from Archavon the Stone Watcher in the Northern wing of Vault of Archavon.

The non-class specific pieces only dropped during the anniversary event from the three world bosses in Tanaris, no?

Or am I misreading what OP wants?

[Sniperorc-azgalor (Sniperorc)]

Good point, I overlooked the “not restricted to Druids” bit.

If they were anniversary items, they’re not available any more (until the next anniversary shindig?).

Recently had that realization myself with the Shaman T7 look-alikes from the event. I was pretty sad about it.

Thanks, that’s the info I was looking for.
Dang.
