Nereus: Ahem. Right, where was I? Ah, right. Other things TRACCS does.

Nereus: See, there’s a reason the shield is set up the way it is.

Nereus: TRACCS makes a physical barrier, instead of one that can be passed through due to volcanic eruptions.
Dysani: due to WHAT
Nereus: Ah, did you not know that this planet is very geologically active?

Nereus: Abellio has a lot of volcanoes under the sea, and their constant eruptions keep the waters mineral rich- Which is helpful when you need to sell that to people but not so much when it’s threatening to disrupt any life on the planet.
