Roselyn

Roselyn or Rose  is a Keidran and the cousin of Euchre.

Appearance
Roselyn has red hair which is tied in a braid and her fur is entirely white, most likely being a Snow Wolf. She carries a knife with a black hand-gaurd and red handle.

Near Death
As Euchre left to the Templar Academy, Roselyn pretended to attack him as a prank. When he explained his plan to join the academy, she desperately tried to convince him not to go, since he would be executed if his identity as a Keidran was discovered.

Shortly before Raine's birth, she ventured into Human territory for an unknown reason, presumably related to Euchre's presence nearby. According to Raine, she wasn't spying for the Wolf Keidran, but she was caught by humans and accused of espionage. When she called for Euchre, a young apprentice (who appears to be Trace) was sent to find him and bring him to the gallows. Euchre, by this time a full Templar and the lover of the academy's head mage, Mary Silverlock, got the message and went to the gallows. Upon seeing Roselyn there, he began an explanation to Mary about her, but, afraid his secret race may be exposed, he stopped and walked away, leaving Roselyn to be hanged.

Due to Euchre's response, Mary realized that Roselyn and Euchre knew each other, stopped the hanging, and interrogated Roselyn through the use of magic. It is currently unknown how much Mary discovered from Roselyn, but it was enough to reveal Euchre's race as Wolf Keidran and for Mary to become furious with Euchre over both his abandonment of Roselyn on the gallows and failing to inform her of his true race before they began a sexual relationship. Afterward, Mary claims to have released Roselyn to Keidran territory, on the condition that she not return.

The Dragon Masquerade
The setting of The Dragon Masquerade is prior to Trace's marriage to Saria, and presumably around the time that Trace and Lady Nora fought to get Saria's attention. Given that Trace would have been around six years old at the time that Raine was born, these events presumably occurred at least a decade after Roselyn was rescued from execution. In the intervening time, Roselyn has become a servant, and particularly a very close friend of Saria's, the two referencing that they have had to hide the fact in the past.

Roselyn is selected by Lady Nora to be the Bearer of The Dragon Facade, a masquerade mask made for Lady Nora every 4 years, which contains a pure mana crystal that won't break despite constant use. Natani, on a mission with Zen, by order of Clovis to capture The Dragon Facade, intercepts Roselyn and interrogates her for the location of The Dragon Facade, before magically impersonating her and casting a sleeping spell on her.

Before Natani and Zen left the masquerade, leaving the Dragon Facade behind as part of a deal with Lady Nora, Roselyn was found in the Flower bed where Natani concealed her, and brought to the masquerade.

Servitude and Current Whereabouts
It is not clear whose servant Roselyn was at the time of the Dragon Masquerade, nor indeed how she returned to human lands after her banishment at all. Since Roselyn was already an adult (or at least adolescent) at the time of Raine's birth, she must currently be at an extremely advanced age for a Keidran, or else deceased.

Personality
Roselyn has been seen to be slightly mischievous, but can serious when needed. She shows great caution with her relatives, as she was greatly distressed when Euchre said he was going to join the Templars under the guise of a human.

Trivia
