Shadow Architect

The Shadow Architect was the leader of the Shadow Proclamation.

Biography
The Shadow Architect appeared to belong to an unknown Near-human species with pale skin, white hair, and red eyes. Another member of her species was present as a servant. She was guarded by Judoon.

When the Tenth Doctor arrived at the Shadow Proclamation headquarters, the Shadow Architect dismissed the idea of his being a Time Lord. After he solved the mystery of the Stolen Planets, she asked him to lead the Shadow Proclamation into war with the Daleks, who had taken them from their places in time and space. The Doctor, pretending to comply, made an excuse to enter the TARDIS and escaped. (TV: The Stolen Earth)

Later, the Shadow Architect oversaw the capture of the Doctor (COMIC: Silver Scream) and put him on trial for interfering with time. Acting as judge, she found him guilty as charged. However after the Doctor and his fellow prisoners saved her from corrupt Judoon and Krillitanes, she revealed the trial was false and he was free to leave. She warned the Doctor he would need his friends around him, "When he knocks the fourth time". (COMIC: Fugitive)
