Yidu

Yidu is a character from the Vikings TV series.

Yidu was an enigmatic woman who was first seen as a servant in Kattegat.

Yidu was first seen in Kattegat among slaves captured in Frankia. She was not the only Asian in the group, but her different look attracted Aslaug, who buys her. She was later shown being cleaned. Her foreign appearance later attracted the attention of Ragnar as well, who strangely looked at her at the hall (as something he had never seen before) and later starts to observe her working outside. She had shown inexperience when holding a chicken, meaning she may have been of rich or noble background. She later revealed she was an illegitimate daughter of the Chinese emperor.

Ragnar led her to believe she was now free from slavery, having taken an interest in Yidu. She provided a drug to help Ragnar cope with his pain, which he subsequently became addicted to. The pair briefly became lovers. She persuaded Ragnar to let her come to Paris. She was later drowned by an enraged Ragnar after she refused to give him the drug and threatened to reveal the secret of Ragnar's guilt.

Yidu is based on Tang dynasty Princess Yidu, daughter of China Tang ninth emperor Dezong.
The drug Yidu gave to Ragnar may have been Opium, but most likely was Betel due to the redness of his lips and excessive red salivation while using the drug.
