Wraith 1 (Daleks Among Us)
From Tardis Wiki, the free Doctor Who reference
A wraith was one of the Wraiths of Lamuria who the Seventh Doctor went to visit to find where the Daleks had taken Kurt Schalk.
He reminded the Doctor that he had to pay up for the information he got. He[who?] then haunted Davros as the Doctor's payment. (AUDIO: Daleks Among Us)
