The Castellan was part of the team who brought the Eighth Doctor to Narvin after Narvin had the Doctor's TARDIS brought to a Gallifreyan space station in orbit around Heron’s World, so he could show him what the Reborn Master had been doing with Sally Armstrong and Molly O'Sullivan there via the Matrix.

They later brought tea to the Doctor and Narvin at Narvin's request, which the Doctor angrily rejected. (AUDIO: The Death of Hope)
