Uriel (The Final Chapter)

Uriel was a Time Lord who secretly wanted to take over Gallifrey.

He and Luther started the Final Chapter, a conspiracy to end Rassilon's policy of non-interference and turn Gallifrey into a military power. They were going to create clones from Uriel's biodata as their army. However, when Uriel saw his "first child"; Xanti, his military ambitions faded and he put his son in the Chapterhouse, then went into hiding. (COMIC: The Final Chapter)
