Vocs

Vocs can exist electronically and physically as advanced holograms. Each of them have a set amount of energy, which acts as a power source and a barrier, and can last them many days.

Generally, powering their holographic forms takes little energy. They only need to sleep when their energy gets low, so they could stay up for several days before feeling tired. Their energy also acts as a barrier, and any damage taken to their hologram forms reduces their energy (such as taking a hit or falling, for example).

Voc Data Chips
If their energy manages to fall to zero, their physical forms will vanish and be reduced to a Voc Data Chip. It’s no cause for alarm, as these chips can be slotted in Shara’s phone so they can recharge. The important thing is to keep these chips safe until they can be slotted

Something interesting to note:

Zephyr’s Voc works a bit differently. If Zephyr’s energy falls to zero, Xephyr can prevent his form from reverting to his Voc Chip by assuming control. It’ll take twice as much effort if someone wanted to mess with Zeph’s Data Chip.
