Champions of Midgard

When I activate a location that would put my Warrior count over 8, do I have to discard the existing ones or from the new recruits?

New Recruits
You are not permitted to take the excess Warriors. If you have 7 Viking Warrior dice already and take an action which says you acquire 2 Viking Warrior dice, you may only take 1 of the Viking Warrior dice you are owed. You choose which you keep and any excess are returned to the supply.
