12:15 P.M., the last set of restraining rings for the portal finished preheating.
At the center of Winterhold Castle's hall, runes snaked over the massive alloy base, abundant magical power flowed along energy conduits and magi-metal tracks, being continuously injected into the arc-shaped metal arm above the device. The ring, covered with runes and crystal structures, had floated to the top of the portal device. In the "cage" structure formed by the ring, base, and metal arm, a twisted space with a diameter of several meters was gradually taking shape.
