Well, there aren't really three things that "bring death back". However, I assume you're talking about the Deathly Hallows. As for them, there is The Elder Wand, The Cloak of Invisibility and the Ressurection Stone. The Elder Wand is the strongest wand ever made (Unbeatable), made by Death from the wood of an Elder tree. The Cloak of Invisibility is, well, a cloak of invisibility, only that this one is a perfect cloak, without flaws or any wear'n'tear. (SPOILER:----------Harry is already in possetion of this hallow.) The Ressurection Stone seems to be the closest item to what you are referring to in the title, in that it has the ability to bring the dead back to life. The only thing is that they are not fully in the world of the living, nor the world of the dead. They appear as a shade of themselves and are never truly happy.

Not all the death eaters die in Harry Potter.
