She was always proud of her ancestors. She was raised by her mother who lives in Moonlight Falls and has only a few memories of her father.
Since being a little girl she has been dreaming of becoming an astronaut, travelling in space. She wants to meet her whole family – even if she has to run across the universe.
Her father died right after her 2nd birthday and although her mother loved her she was a bit ashamed of her daughter being an alien.
Marleen’s family is full of weirdos (witches, werewolves etc.) and she was the only "normal" person. She might have been envy of them but she never said so. What does she see when she looks at Nymphea? Herself, but with strange eyes. Who is capable of powers she will never have. Jealousy at its finest.
Her mother’s behaviour influenced her social interactions. She was shy and never talked to anyone at school. Maybe that’s why she fell in love with her imaginary friend. Thanks to her aunt Moira’s amazing skills Lycopersicon became a flesh-and-blood sim.
They now have two sons, Nipudus and Zorlack.
