I've a question pertaining to the second character I was considering, for if/when we get around to that point.

It's clear that a person who is naturally unable to access their Arcane network can use specialized tools to in order to make use of it. What I'm wondering if someone who has been forcefully sealed off from their network would be able to use a similar tool (likely created by a Machinist) in order to access at least a portion of the power they once knew.

The idea I'm going for is an ex-Diver who got out of control and crossed too many lines. For his/her crimes, they were imprisoned and had their Arcane network sealed. With the advent of the Arcadian Survey initiative, they were given another chance to put their experience to work. Unable to directly use their own Arcane network, I was thinking they would use one or more foci of sorts (staff, rod, ring, gauntlet, etc) that drew from them directly but were rather limited as to the variety of magic effects each foci could produce.

The sealing of one's arcane network is the process of stopping its flow at the base of the brain-stem, so it would be difficult to access it with tools, but not impossible.

It would require that tools have a direct link to the brain, otherwise accessing a sealed network is impossible. Of course, finding such tools would be extremely difficult, especially since harnessing arcane energy straight from the brain can be extremely dangerous. The results could vary from amnesia, to headaches, to hearing voices, to pretty much any array of mental disorders.
