Volendrung is a Daedric artifact since it's always associated with Malacath.Volendrung was unique as well and one of the MH guys was showing it off during beta. They're not above giving out unique items as Legendary/Mythical/Superdooperüber from that as an indicator. Granted, Volendrung was not a daedric artifact to the best of my knowledge, so maybe that's the tie breaker.
