Higher species

"Higher species" or "higher forms" was a term used to refer to species who were aware of the Time Lords and the Last Great Time War. Doubting the Tenth Doctor's identity as a Time Lord, the Shadow Architect stated that the Time Lords were the "stuff of legend" and that they belonged in the "myths and whispers" of the higher species.

According to the Gelth ambassador, the Last Great Time War was devastating to "higher forms" yet invisible to "smaller species". (TV: The Unquiet Dead)
