[Cyber-Slig]

Because oddworld is focused on old rusty technology and a mix of native villages.I dont think vykkers would have time travel technology.If they did they could go back all the way back in time to rupture farms and slaughter abe....but in the flashback you could see how the glukkons turned not by a story but with youre eyes.Like they saw the moon and the glukkons got mad cos of it.They went nutso but couldnt do much to the muds except slap em with big massive hands.They could have then run to the woods and called on the sligs.Could be cos they are cousins of a sort (no arms = gluks = no legs = sligs even though gluks have legs and arms the legs are disable and dont count as a part of the body really)
