SO I found this video today on yourtube, I t gives very good information on everything that Cyrodiil brings. This is NOT from the Devs or brand new information but i thought these guys did a very good job of telling you every aspect about Cyrodiil. This is a very good video to show to someone that you want to explain TESo PVP to. The ex DAOC player will love this.
