One good option could be 'Nightshade'. It has a very mysterious and slightly dangerous connotation, often associated with poison in some cultures. Another is 'Mistwalker'. The idea of walking through the mist gives an air of mystery and the unknown. 'Eclipseborn' also works well as it ties into the idea of something being born during an eclipse, which is a very rare and mysterious event.
Consider 'Gloomshroud'. It gives a feeling of being covered in gloom and mystery. 'Abysswhisper' is also very mysterious. The 'abyss' is a deep, unknown place and 'whisper' implies secrecy. 'Soulstealer' is a very dark and mysterious last name. It makes the reader wonder what the character has done to earn such a name and what kind of power or curse they might have.
