Adrian happily activated the Dimensional Teleportation skill when the giant researchers were done surveying the Chaos Springs. Adrian also warned them to not return back to the Chaos Springs after the reset as they would need to face all of the golems again or be sent to a different pocket dimension.
They were only able to meet Adrian because he was inside the Chaos Springs. Adrian also hid the fact that there was another gate to the Silver City in the Hidden Spring. The Fallen told him to never tell a soul about it or else the angels will definitely decimate the kingdom of the giants.
Adrian also strictly warned them that they should never open the gate. It would leak energy again that attracted the angels. The giants thanked Adrian for the information about the Chaos Spring. Adrian only told them that the Fallen are protecting a Nephilim which made the giants even more assured to never open the gate.
