His mouth falls open, perhaps to say something, perhaps in simple shock. "I-...ah-..." There are a few more struggles for words before he gives up, looking back to the portal.

Ears low, he numbly walks over to it. Gazes into it for a long while.

Then with an angry growl that growls into a furious yell, he waves his staff and the portal collapses with another loud CRACK. Nothing remains of it except the sigils and circles drawn into the floor and a few faint sparkles hanging in the air.
