Thalia was a Lord Chancellor in the High Council of Time Lords.

Like all Time Lords, Thalia was taken from her family at the age of eight for the selection process in the Drylands. Staring into the Untempered Schism as part of a Time Lord initiation rite, Thalia was inspired by what she saw in the Schism. (PROSE: A Brief History of Time Lords)

Thalia was one of the High Councillors who sentenced the Fifth Doctor to death to stop Omega from taking over his body. (TV: Arc of Infinity)
