Ukkan

The Ukkans were an all-female race of librarians native to the planet Ukko.

Biology
Ukkans were light pink-skinned humanoids with enlarged purple craniums and around a dozen purple tendrils from the head. They had long fingernails, purple lips, dark yellow eyes and spots of the skin resembling Human freckles. They were able to live for millenia.

Culture
They preserved endangered planets in holographic form to keep them safe.

Technology
The Ukkan's mastered or as K9 Mark 2 noted "mistressed" the art of archiving, they could reduce a whole world to an infinitely compressed hologram which they filed in their archives as a Library card. K9 compared it to squashing the data when you zip a file on a Computer. They used goggles to protect from the card's effect of transporting the observer to the planet although they grew immune to it over millenia. They used retrievers to take people out of the cards.

History
Due to the endangered status of Urlic being the last planet of the Catorkian Galaxy, the Ukkans archived it into a Library card. However, it was taken from their archives by Huskian Pirates. Eventually the card found it's way to Earth and it was acquired by The Department. As there was a prison over-crowding problem on Earth in 2050, Inspector Thorne decided to turn it into a prison colony and dump prisoners there. He lured Starkey to it in a careers day in Department HQ, when Starkey found it's card he was sucked in and transported to the planet. Darius Pike brought it to the Gryffen House, they need the plinth of the card to bring him back. K9 Mark 2 and his friends tricked Thorne into giving it to them so they could release Starkey then give the card to him, they gave him a pair of goggles which provided immunity to the card (which Yssaringintinka disabled) and he was transported to the planet. The Ukkan librarian Yssaringintinka was able to return them. (K9TV: Lost Library of Ukko)
