The High Aldwin
If you felt there was no other better option than Tempest, then at that point you wanted it to win.It was clearly the best option in the list, and I only switched to Tempest for lack of a better option.
Obviously, even though it wouldn't be hard to do.But you're right about one thing, I don't want to retcon it.
It wouldn't be trouble at all. If nothing else, you go back to the contest at the point when Light was mistakenly removed and continue from there. People can still vote, after all.The trouble with a retcon, as @DeviousQuail says, is doing one fairly, while upsetting as few people as possible. That is the real damage to the "validity of The Survivor thread," if such a thing exists.
Grave Domain 4
Knowledge Domain 10
Light Domain 1
Tempest Domain 6
The only other fair thing I can think of is to include both Domains as finalists.If enough people agree that some sort of special exception should be made, I'll think of something (it still won't be a retcon or a rematch, tho.)
And FWIW, you might consider these popularity contests or whatever, but for people voting ignoring a mistake is basically telling them your vote doesn't really matter. If that's the message you want to send, that's your choice.
