Yesterday, Visionary Realms and the people who are creating Pantheon: Rise of the Fallen, announced that users only have 3 more days (two more days as of today) to pick up either a Knight's or a Patron Pledge before they removed!  This means you will not be eligible to participate in Alpha testing unless you subscribe to a Champion or VIP pledge.

From the VR forums: 

"There have also been questions regarding subscriptions being used towards these pledges. As a reminder, pooling of subscriptions ended on January 22, 2016. Any subscriptions paid after that date are not eligible for pooling towards a pledge.

Just remember folks, there are only 3 days left to grab the Knight's and Patron Pledges before we remove Alpha testing as we near our testing cap for players, check out the full post here: https://www.pantheonmmo.com/content/forums/topic/3922/new-pledge-tier-coming-september-12th

Hi everyone. Just as a clarification to Kilsin's reminder, Alpha testing is being removed from the pledges that are going away only, not from any Champion pledges or VIP pledges. Anyone who pledges at Knight or Patron before they go away will indeed have their testing access honored, once testing begins. There is no client to download yet as we are still in internal testing only.
