Steward's Tomb and Terrible as the Dawn

[Tunadan]

While at Steward's Tomb , can the Freeps player choose to discard two Elves to prevent the wounds from Terrible as the Dawn to Galadriel?

[Orophoin]

Yes they can discard. The thing you are preventing is the effect of the card, not the wounds themselves

The key phrase is 'to prevent this'. For a start, if the intention was to prevent the wounds (plural), rather than the action (singular) it would be 'to prevent them'.
