Is there a timeline anywhere or can someone give a quick timeline of when each of the TES games takes place chronologically? I thought Arena took place in the first era but Uriel septum was emperor so that would be third era right? And what about daggerfall and redguard? Thank you!

There was more than one Uriel Septim, I believe.

And the main TES games are in the third era but Skyrim which is 4th., it is just Redguard was in the 2nd era and TESO will be too.
