Grayla

Grayla was briefly a companion to the Tenth Doctor.

Biography
Grayla was a Gråttite, born on the planet Grått. She grew up hearing stories of the Mörkön and how it would terrorise the planet if they showed any emotion. However, she was a vibrant and passionate person. Grayla grew bored of the planet and travelled into the stars.

Whilst travelling, she met the Tenth Doctor. She travelled with him for a while and he showed her the things in the universe she wanted to see. However, before long, she wished to return to Grått.

Upon her return, Grayla wished to change things. She told some of the younger Gråttites of the things that the Doctor had showed her and that they shouldn't hide their emotions the entire time. This caused many Gråttites to believe that the Mörkön was a myth invented to scare children.

Many people visited the Whispering Gallery and began to mourn their loved ones. The grief awoke the Mörkön and caused him to kill all in its path. The monster had been trying to find Grayla, whose intense emotions acted like a beacon. Grayla refused to leave the planet. She was tranquillised and kept emotionally numb until her death, allowing the Mörkön to return to its slumber.

Her last thought was held in the Whispering Gallery and was a message to the Doctor:


 * "Doctor, they were right, they were right all along. This is no place for emotion. When you come, you must remember that."

When the Doctor visited Grått, his grief over Grayla's death awoke the Mörkön once again; however, his wealth of positive and negative emotions overwhelmed and destroyed it. He revealed to the people of Grått that Grayla would have been able to do the same thing, had they not sedated her.

In light of this information, the Gråttites erected a giant statue of Grayla in memoriam. (IDW: The Whispering Gallery)

To date, Grayla is one of only a few known companions whose death the Doctor has learned of after their travels (although, as a time traveller, he is presumably aware of the ultimate fates of many of his companions, few incidents of this nature have been chronicled).

Behind the scenes

 * Although not directly stated in the comic, the fact Grayla travelled with the Tenth Doctor before he met Martha Jones would mean she had to have travelled with him sometime between the events of The Runaway Bride (which followed directly on from the departure of Rose Tyler) and Smith and Jones (in which Martha debuted), unless there is an unchronicled interval during the Tyler era in which the Tenth Doctor travelled alone (possibly circa the events of Attack of the Graske).
