Delia isn't like other human. She was born with unique abilities like;
Precognition
Time travel (not yet learned)
Portal Creation (not yet mastered)
Personal portal (not yet mastered)
Teleportation
subspace travel (not yet learned)
Portal sensing
and more in development
She was called human wanderer because how she behaved and acted. Being able to move around using portals and not staying in one place.
Fun fact: She never learned how to create a portal for her ownself or even whenever she wants. They just show up. The places she dreams is where the portals usually takes her.
(p.s. This is written in her journal. She is very sensitive about people peeking through her personal stuff including the secret notes she writes down.)
