The reward is the weapons, at least as far as we know from what we've seen so far. It might be the same reward as you get from lower level fates, but that doesn't mean there is no reward.

@Hyrist: Yes, a very good solution would be to put the costume items on the vendor for purchase with the tokens you get from the fates, just like the past two events.
