I have these terrible ideas about new Elder Scrolls in Cyrodiil that I actually don't want to see in pvp but I want to write them here:
A new Elder Scroll than you can put in your own keeps to get benefits or move it to enemy keeps. While attacking a keep with this scroll in your hand you and your allies get a blessing increasing your damage done but you and your allies also get a curse reducing your healing done and healing received.
A new Elder Scroll that you can move around. If you read this scroll you cause enemies around you to be blinded for 3 seconds but it also causes your allies to lose 80 percent of their max health. 30-minute cooldown.
Write your own crazy terrible ideas about pvp that will actually never happen but you find them interesting.
