The Champions of Olympus returned back to the surface using the emergency gate that is placed at the bottom floor of the Ruins of Etna. This can only be activated by relics provided by the Olympian Gods which is why only they can activate it when they are in the room. Seeing that only the first seal shows signs of deterioration, they immediately reported it back so that the seal can be fixed by another demigod that has that kind of ability.
When the Champions of Olympus finally vanished from the room, the space suddenly began to shift as the statues of the Olympian Gods that were in pristine condition started to turn old and looking close to breaking. The entire room finally returned to what it truly looked like and it was none other than a very old looking altar that is not dedicated to the Olympian Gods but the Primordial Calamity Typhon.
