Many of the actors cast in the episode are Irish and some scenes seen to take place in early 20th century Ireland.
Not mentioned on the cast list for the TV listing but mentioned on the BBC website as cast in Ascension of the Cybermen is Ian McElhinney. There are rumours of a character named Tectian so perhaps this is the name of McElhinney’s character.
