The Solego Circuit is a device created by the mad mad thinker Solego that opens portals to other dimensions. The unstable portals could however cause the destruction of the world. Taurus Bulba and Dr. Thaddeus Waddlemeyer used the circuit to create the Ramrod. After F.O.W.L. stole it, mainly stolen by Steelbeak from Drake Mallard, Bradford Buzzard used it to create a void intended to destroy anything associated with adventure and chaos called The Solego Vortex. The Solego Circuit is one of the missing mysteries of Isabella Finch.
