Tower fall

"Deactivate all other portals now!" The elder realized that the situation had just changed from something troublesome to a real risk. He was strengthening his body to the maximum to resist the suction of the anomaly, but everyone else who wasn't in the control room was unable to resist.

The employees inside the control room obeyed his orders and all portals that were about to be loaded were cancelled, but those already active could not be deactivated until all their energy ran out.

The anomaly was growing by the second, its shape changing more and more. Dozens of staff and mages had already been sucked in and presumably killed. The nearby floor and walls were also swallowed up without resistance, although the runes should have made the floor as strong as adamant.
