Titania was born a normal human girl called Maryrose living in poverty with her grandmother during the Middle Ages. When she was collecting wood in a nearby forest, she was tempted by a group of Flitlings to return with them to Faerie Once there, she became a favorite of Queen Dymphna, earning the nickname Rosebud to protect her true name: she also caught the eye of King Obrey, who - spurred on by his jester the manipulative Amadan - magically transformed his wife into a tree and took Maryrose as his second wife. Maryrose took a gemstone glamour from Dymphna and used it to appear a pure-blood faerie at her coronation, taking the name Queen Titania.
Titania seemed truly flattered by the love and attention of the king, but this was short-lived: Obrey was killed in battle by the rightful King of Faerie, Lord Auberon Seeking to reunite the warring factions, Auberon took Titania as his wife when he reclaimed the throne, and urged her to quickly set about the work of producing an heir to make the union secure. Titania felt slighted by the loss of a loving husband and his replacement with one whose only interest in her appeared to be political, and soon began the first of many affairs with the human falconer Tamlin. Titania's infidelity later became notorious - even one of her lesser subjects was able to comment on how fitting it was that Auberon wore horns - and she is rumoured to have had an affair with Dream of Endless (called "Lord Shaper" by the faeries) and was seen casually bedding her female servant Selwyn - unaware that the maid was Auberon in disguise. Perhaps because of her own infidelity, Titania was quick to assume that Auberon was equally unfaithful although no evidence of this was ever shown, and conversely Auberon was shown to maintain strong affection for his wife even if the face of her reputation, even regularly disguising himself as a maid to be with his queen without enduring her scorn.
Titania was shown to be a jealous lover, demanding unconditional adoration from her lovers even though she rarely returned the feelings herself: her affair with Tamlin ended when he realised what she was truly like and she was noticeably annoyed when Dream sent no secret message for her with a servant who returned to Faerie from his realm. However, she has also shown genuine affection and emotion, even if she tries to hide it: when her affair with Tamlin leaves her with a human son (possibly the powerful magician Timothy Hunter she is devastated to have to send him to Earth to keep the secret of her nature and her affair from the King and risks sending her entire realm to war against Hell to protect her son with Auberon from being kept in Hell as payment of Faerie's tithe to the demons.
Titania was acutely aware of her status as queen, and the respect and attention she felt she was due because of it. She nearly caused the destruction of her entire realm by cursing Molly O Rielly to turn her into the "Burning Girl" for no other reason than her attendants' fascination with the girl's efforts to grow real vegetables, and frequently grew enraged at Timothy Hunter's casual disregard for the possibility that she might be his mother. However, rarely, she can show something like humility, for example apologising to Molly for the trouble she caused the girl and acknowledging that she had done wrong. Despite her faults, Titania was a strong and able queen, whether riding out to face down the forces of Hell at the head of her army or subtley politicking to ensure that Faerie's best interests were met in the wider worlds
