Aread would go ahead and click the button as well. It seemed like it may be a helpful boon, and install some quick software updates or expansion packs and whatever else. It typically felt easier to download all the content up front, instead of incrementally along the way. That way, he didn't have to worry about forgetting it or anything else weird like that. It's happened once or twice in other MMOs with 'locked content' areas.

Before the entire screen would blast a [b]blinding[/b] white light. 
If someone could stand looking at it for a moment, they would see the vague outlines of three eyes staring at the observer, along with a set of drooling, sharpened fangs leaking onto the void.

Things would shift again as the vague 'haze' of the game's last image would rapidly approach toward the eyes. 
Practically charging and then entirely overlaying one's field of vision. Until it seemed the game itself aimed to entirely impose itself onto the players' retinas, forcing them into a first person view of the game.
Although, it would likely extend beyond that. As whatever unnatural force was involved, not only tried to put the players' in the perspective of their game avatars, but fully inserted into the avatar's bodies as well.

A presence in the background fading with a pained laugh.

Aread would be on his knees in the middle of the sidewalk. Reactively clinging onto the staff for balance, despite the fact the half-fae looked almost ready to hurl. It looked like they didn't have a pleasant experience either.
