It says that she's Haltmann's daughter, but she looks too different. I think she might have been damaged by the trip to Another Dimension, and someone found her and brought her back.
To tie this into my au explanation,
I noticed her similarities to The Mages, who, in my au, are elemental energy beings from Jamba (Highness's homeworld) who, in order to survive outside the areas affected by the magical rifts, are given protective orbs to dwell in, which are usually decorated. The Jambans run experiments trying to open portals to Another Dimension in order to try and locate Halcandra, which had been relocated eons ago by the dying inhabitants to prevent their enemies from getting access to their unusually powerful magical rifts.
eons ago, the Jambans were still living in primitive tribes, and were jealous of the power the visiting Halcandrans possessed and would not give to them. Nowadays the Hal are remembered in their mythology as greedy monsters and/or evil tricksters. The ones who believe they actually existed have a hatred for them, and wish to possess their power.
During an experiment with portals they brought Susie through and helped her with their technology, perhaps with the orb tech the energy beings are given. She eventually leaves to reunite with her father.
