Xylandras was a Spectre encountered during the quest Duchy Get Quest (Part 1), when she visited D&P Pizzeria and Saladeria in the Millennium Forest to harass it. She was a haunting hooded figure, part-skeletal corpse and part-ghost, wearing a chrome breastplate, faded purple cloth-wraps, and a long cape, buttoned with dead and rotting flowers; a black jewel was embedded into her neck. She carried a wooden pan-flute embossed with black lacquer, and a gilded lute, and when she performed, ghostly duplicates of her would surround her. She also had an umbrella to protect her from the sun.
She was a frequent visitor, and challenged the Pizzeria's patrons to battles of lyrics and music, reaping their souls when they would lose. She seemed to be able to turn her victims into Neznámy as well, as seen with Lorrent Cleanblade, a Fey knight that challenged her. He was released and Reincarnated later, however, as some kind of giraffe-esque Fey.
Syltorin Margaster and Dolen Harven managed to win, despite her foul play and attempts to break Dolen's instrument. They got her gilded lute as a reward and banished her from the establishment.
Together with Sirxus and Meinzer they defeated her in a fight when she tried to leave, enfeebled her by sunlight exposure, tracked her down when she fled and hid in a tree, and trapped her in a large rectangular lantern that she offered. Since she was a Spectre, she claimed that she would return even after her destruction, until there was no unfinished business left, so the group decided to put her to rest by helping her find her home, that called to her with music. This was south of the Pizzeria.
Pranke, as thanks for dealing with Xylandras, threw a large party in her Pizzeria, and even named some dishes after Syltorin, Dolen and Sirxus. Rumours about their deed spread, and helped the Prince find himself in good graces with the Fey of the Pines.
