Lore
Zac, the Secret Weapon
Zac is the product of a toxic spill that ran through a chemtech seam and pooled in an isolated cavern deep in Zaun's Sump. Despite such humble origins, Zac has grown from primordial ooze into a thinking being who dwells in the city's pipes, occasionally emerging to help those who cannot help themselves or to rebuild the broken infrastructure of Zaun.
