Oculeth's theory is sound. Reckless, but sound.
A small warp-field could trap and excite ambient mana in the conduit, thus creating a manastorm similar to when the arcan'dor fell out of balance.
I can build a device to generate the warp-field, but I need materials.
Specifically, warp-resistant alloys - such as the armor plating of high-end security constructs in the noble district.
Those constructs are deadly. If anyone owes you a favor, now is the time to call it in.
