Hailing from Zelem’s Nexus, Vex grew into his full teleportational strength because of Crogenitor Zelem himself.

As one of thousands of technicians assigned to maintain the Nexus teleportation network, Vex knew the grid completely. He did not know that constant exposure to the network’s quantum-gravitic, temporal and wormhole distortions were poisoning him. Nor did he or Zelem know that those quantum-gravitic energies were mutagenically unlocking Vex’s latent ability: individual, self-directed teleportation.

When Vex first accidentally teleported from inside the Nexus out to the vacuum of space, he reacted instinctively, teleporting towards what he energetically sensed was the safest zone: Zelem’s enclave. Alarmed by the grotesque alien in front of him in a region he didn’t know existed, Vex immediately attempted teleporting away.

Quantum-jumping around the enclave again and again, Vex destroyed whatever he could to escape the strange alien he perceived as a captor. Growing more powerful with each ’port, Vex gained the power of temporal sabotage--the gravitic warping of time-flow. He slowed Zelem himself with that power, and would have destroyed him if not for Zelem’s wiser defenses.

’Porting away, Vex realized the strength at his command. When the Darkspore invaded soon after, he deployed his powers against them as what he’d become: an unstoppable, unpredictable teleportational warrior.
