Nope!

I'd say it's likely that Piercetree went first, then Eagle, then Leenile (though Leenile could easily come before Eagle just as well).

Leenile, Piercetree, Eaglebloom, and Grousemane lived during Alderstar's and Myrtlewing's reign (they were serial killers and hid many bodies). Because of them, many cats from the Clans went missing, and these four were chosen to go find them (Grouse from ShadowClan, Leenile [Creekfire] from WindClan, Eagle from ThunderClan, and Piercetree from SkyClan).

Piercetree:

On the journey, Grousemane and Leenile died by accidents. But Piercetree's leader found it suspicious that no one went missing while they were gone, but two cats happened to die while out with Piercetree. He was a very strong cat, huge and muscular, and he could easily have killed many. So, he was executed just to be safe.

In StarClan, he was furious, and when he confronted his leader (when that leader came to StarClan), he didn't even receive a sincere apology, just a 'whoops my bad' kinda thing and excuses. In a fit of rage, he attacked and killed him, and was chased into the Dark Forest.

Leenile:

Leenile was very upset at all the innocent cats suffering in the Dark Forest, including kits.

He would loudly argue against it and get cats on his side. He was told multiple times to stop and never listened, and some other cats tried to physically fight him. He got the blame, word spreading that he was becoming 'violent' and he was exiled (yes it's bullshit).

Eaglebloom:

Similar to Leenile, Eaglebloom was upset at the injustice. He would take prey and herbs and sneak them over to the Dark Forest. He got caught and was told to stop, but like Leenile, he didn't listen and kept doing it.

He was exiled for 'aiding dangerous cats.'

(It's possible this began after hearing Leenile's speeches).

Cautionary Tale: ??

Story:

He went on the mission to search for the missing cats. Though he wished to find his Clanmates, he was lucky that none of them were terribly close to him, and all of his family was safe in camp.

He was also lucky because he was one of two to return to the Clans alive. Grousemane had been hit through the throat by a long Twoleg object, and Creekfire had died after a speeding monster flung a rock at his head.

Lucky, lucky, lucky. He was so lucky.

What about the others? What about those that weren’t so lucky?

What about those that had to starve, had to just deal with terrible death wounds and infection just because of mistakes they made in life? 

Some deserved it, yes, Myrtlewing and Alderstar especially. But they didn’t represent everyone. Mothers were condemned for protecting their kits. Apprentices were condemned for protecting themselves from bad mentors.

Eaglebloom couldn’t protect his Clanmates, picked off one by one. 

He couldn’t protect the companions he had made on that mission, or when they returned and Piercetree was executed simply because his leader thought that it was suspicious two cats had died while out with him.

He couldn’t prevent Creekfire from being exiled into the Dark Forest--the final straw on his back.

Eaglebloom was tired of always being the one able to get away, he was tired of being lucky while others suffered when he could do something.

So, he did something.

It wasn’t as if it was anything big. He would simply sneak prey and the occasional herbs to the border for them to be used by anyone to grab them.

The problem, perhaps, came when Eaglebloom was found out and told to stop.

Then told again, and again, and again.

Finally, it was no longer tolerated. He was kicked out of Starclan. 

Furious, he left, but not before taking a final mouthful of mice and berries.

Additional Information:

--Eaglebloom was exiled very shortly after Creekfire (Leenile). Piercetree is also exiled around the same time, about two moons or so later. His story is next!

--This was, of course, before the Dark Forest-Starclan negotiations.
