Zabrina invented the theory behind the Spelljammers,which would allow for inter-planetary travel through the Void, while she was a journeywoman at the Universitas. The Universitas, long since a subsidiary of Ego Ultd., kept her invention proprietary to maximize profits. Meanwhile Zabrina created her own prototype in secret and used it to escape the corporation's clutches. There are many legends about her exploits after her escape but all we know for sure is that in the wake of her escape Spelljammers began popping up throughout the core, triggering the start of the age of connection.
