I'm not aware of the existence of any 'Legion of Chorrol'. The Second Legion was headquartered in peacetime in the vicinity of Bruma. Caudex was stationed at Fort Warden, which is somewhat close to Bruma, but that doesn't really confirm he was therefore a member of the Second Legion.About the captain Caudex
Was Captain Caudex a member of the Second Legion or the Legion of Chorrol ?
I imagine that the Second Legion was in the Imperial City when Planemeld began ... and that its members were trapped like other legionaries from other legions (which ones legions by the way?).
We find a woman named Caudex on Chorrol ... A member of his family ?
Legion Zero did not exist before the Planemeld. It was created out of legionnaires that were inside the Imperial City and drank the Blood of Molag Bal. Many Legions were recalled to the Imperial City, so I assume Legion Zero consists of soldiers from multiple Legions. However, it seems to contain atleast members of the Fourth Legion, since this conversation takes place with Quintia Rullus in the Elven Garden District:About the Legion Zero
Was the Legion Zero created during the Planemeld or was it just one Legion among others existing before the Planemeld ? Opinions differ among players on this subject.
My best guess is that General Velarius was in command of the Fourth Legion (see above).About general Raetus and Velarius
What legions were they in command ?
I do think Quintus Verres is part of the Seventh Legion's invasion of Hammerfell. It's a bit too much of a coincidence for him to be there if he wasn't.About Quintus Verres
Is Quintus Verres a commander of the second cohort of the seventh Legion ? This cohort was tasked with finding a device in the ruins of Volenfell.
The Seventh Legion landed at Satakalaam... and was defeated there.
Is Quintus Verres a member of this legion or is it a coincidence ? I imagine that Captain Candidus was working with Quintus Verres.

And the Colovians rose behind you! After an initial defeat at the hands of the Emperor's troops at Fort Ash, you took command of the Legion of Chorrol and sent Leovic reeling back into the Heartland. Word spread that Cyrodiil had a savior, and that Reman's true heir had come at last. The Colovian Estates rose as one under your Dragon banner, and eastward you marched.
