In the official ZOR (Zenith's Outer Reach) lore, it's said that protogens are the ancestors of primagens, their successors.
"Primal" usually refers to something that is of the dinosaur age, which usually means it is more ancient. We tend to think that things that are more ancient are worse than what we have today. However, the lore disproves this assumption when it comes to primagens.
We only think that primagens are primal because of the prefix: "prima." But you must also consider that protogens are only a prototype; which is where the prefix comes from.
I already have them split in the form of screenshots. I'll try to find some way to send them all individually. If you want, you can memechat me and that would potentially be an easier process.
