Easy one - name two beings who live inside a power ring.

(I'm thinking of two specific beings, but if someone knows of more than those two...)

Myrwhidden, Parallax.

Well, I'd say you're half right.

Does Parallax live inside a power ring?

Or did Parallax live inside the central battery?

I don't recall, it was a guess.

Since I don't recall either, the thread is yours.

(I was thinking of Mirwhydden and Volthoom)

In a somewhat famous story, Green Arrow accidentally kills a criminal and exiles himself to a Tibetan monastery. The kill was caused by an lingering injury to his shoulder that he received in yet another well-known story. What story was that?

Longbow Hunters..?

Nope, not that one.

Was it that story where he and Green Lantern were chained to airplane tail sections, on either side of a pollution activist who looked suspiciously like a certain religious figure?

No, but that injury is referenced in that story as well, IIRC.

Actually, Parallax doesn't live in a ring or in the Central power battery. After the whole Sinestro Corps war, he was split into four bits and put into four seperate power batteries. Hal's, Kyle's, Guy's and Stewart's.

Here There Be Dragons.

Oh shucks! Does that mean I get the thread back?

No... but if IgMo is found locked in the trunk of a car that's been pushed off a cliff, you might be a suspect in the crime.

Nope.

Also, don't feel that you have to have the exact name, a description will do. And it's a very very famous story, moreso than any of the others mentioned, even in the original question.
