The Spirit Realm

I have been told of several new augments with DoD. They are:

1.
2.
3.
4.

I can find no information on Allah's or on Lucy (or anywhere else for that matter) about where these augments drop and whether they are raid events or groupable. Anybody have any ideas? I would imagine the Petrified Drachnid Egg is a raid event aug, as it's on par with Vishimtar's Heart and some Anguish augs. The others, I can't place.

Help would be appreciated, I'd like to keep my augment tables as up-to-date as possible. Also, if you have heard of other augments, please give me some information about them. Thanks guys.

Egg is definately raid, it's from Sendaii, the Hive Queen. An event not for the faint of heart, at all.

Heart of Darkhollow Wilds is from Antraygus, the Spore King. He's not challenging in the least, but pops some adds, so just barely stays qualified as a raid encounter.

Conqueror Stone comes from the one group (heavy hitter style, but still one group)encounter "The Keeper", fourth mission in the level 70 spell series from Jarzarrad the Prophet, the Hard version. Voyager Stone same thing, just the caster parallel.

Found tonight as well.
Is this from the Hive Queen raid event too?

No, that's from Dreadspire
