Where can I get rebirth shards?

[Viiikcsii]

Crystal Saga II is totally new for me. Everything's changed... And there is this item named rebirth shard. It is for the level 35 Rebirth armor sets.

So my question is... Where can I get these Rebirth shards? Does a boss drop it? If yes, wich one? Which instance should I clear to get it?

One further question if anyone knows the answer... Where can I get the other shards (Ancestral shards, Soul-crusher shards, etc.) from?
Thank you very much for everyone (anyone) who repies.

Nevermind, I found out.

Dreamwalker Shards - Bizarre Dreamland
Rebirth Shards - Nirvana Domain
Ancestral Shards - Sacrificial Relics
Soul Crusher Shards - Soul-crusher Forest
Mistweave Shards - Psychodelica
Atonement Shards - Exelorn Hollows (you will also get Enchanted Skill Dust Shards here, needed if you are upgrading from Mistweave to Atonement with shards)

Normal, Hard, and Nightmare all drop shards. Nightmare also has a chance to drop actual gear, saving you from needing to gather the shards.

If you want to read about more drops in these dungeons, the level requirements, and where the dungeons are located, open the Event panel (flag icon above the shopping cart, next to the mini map), click the Dungeons tab, and then click on each dungeon name.
