Talent Scout
It should be relocated at Talent Scout because The Rise and Fall comic story clearly shows how Talent Scout is created from the main mass of Entity at the same time as the small portion of the Entity is destroyed by the Doctor on Rokhandi World. There is a clear continuity. There must obviously remain a separate entry for ARC, and probably a separate entry for the whole entity's origin planet, made of the same stuff. In fact, the categories already come from Talent Scout rather than form the amorphous entity.
Talk about it here or check the revision history for additional comments.
The Eleventh Doctor and Alice Obiefune encountered a portion of an Entity on Rokhandi. August Hart had it caged in the Rokhandi World amusement park. It fed on a lifeform's desire to cause trouble, making them docile. Hart was feeding people to it to make them obedient park employees.
When the Doctor was fed to the Entity, it could not process the Time Lord and was destroyed. The employees were restored and staged a revolt against Hart. The rest of the Entity was also damaged by the fragment's destruction. (COMIC: The Friendly Place)
