Krafayis

The Krafayis were a species of space-faring omnivorous predators.

Biology
The Krafayis were large creatures with reptilian and bird-like traits. They had parrot-like beaks, quill-like horns, two wattles on the sides of their heads, long necks and quills down their tail.

The Krafayis were generally invisible, giving them the perfect defence. They could be seen by Vincent van Gogh (apparently due to his unique perception of the world) and in the reflection in a mirror on the Species Matcher. (TV: Vincent and the Doctor) They could also be seen in other reflections, such as in water. (PROSE: Blind Fury)



Life cycle
The Krafayis were somehow capable of travelling through the universe, moving from planet to planet to hunt. They preferred to travel to planets with oxygen/nitrogen atmospheres, such as Earth. They hunted in large packs with a strict hierarchy and had territories which spanned star systems. Eventually, they would depart the planet, leaving behind the weaker Krafayis. These Krafayis would be unable to rejoin the pack and in their loneliness would cause destruction and chaos until they were killed. (TV: Vincent and the Doctor)

History
The Krafayis were believed to be an ancient species. Legends say that in the Old Times of Gallifrey, a Krafayis attacked the village of Slothe, killing many. A Gallifreyan, Presus, eventually confronted the Krafayis and after three days of fighting, the Krafayis was killed. (PROSE: Blind Fury)

At some time before 1890, a pack of Krafayis came to Earth, fed and left. One blind Krafayis was left behind in France, where it attacked several people. It was also seen by Vincent van Gogh and painted into The Church at Auvers.

When the painting was seen by the Eleventh Doctor and Amy Pond, they travelled back to before it was painted to investigate. During the visit, they saw the remains of one of its victims and were later attacked by the Krafayis itself. The Doctor was eventually able to identify it and planned to confront it in the church, stunning it with his Sonic screwdriver. This attempt failed, and the Doctor, Amy and Vincent were forced to hide. The Krafayis followed them and attacked, forcing Vincent to fight back and accidentally kill it. Following this, the timeline was changed and the Krafayis never painted into The Church at Auvers. (TV: Vincent and the Doctor)
