Greater Old One

From Tardis Wiki, the free Doctor Who reference

The Greater Old Ones, like the Great Old Ones, were the elders of the Guardians of Time and their word was law. (PROSE: The Quantum Archangel)

Behind the scenes[[edit] | edit source]

The Grace, the creators of the Key to Time, were described both as Great Old Ones[source needed] and as superior to the Guardians in The Judgement of Isskar and The Chaos Pool.
