All of the Avengers were in Tony's mansion having a party, Tony invited other famous people and guests too. The Avengers were in the living room sipping their drinks and chatting then suddenly a portal appeared on the ceiling, everyone turned and looked, a few guests were shocked or scared

"everyone calm down, it's fine" Tony reassures everyone

"it's fine? we don't even know what it is.." Steve says.

Natasha, Sam, Wanda, Bucky, Thor, and Clint all look up at the portal
