What to do . . . ?

[BONUS]

Now . . . what to do?

I was pressed into a hard place here. My [Teleport] was in cooldown, and it would take until tomorrow for it to reset. Tomorrow afternoon exactly.

With this Grendelkin's speed, it would reach Town in an hour. Or even less. 

Not only that, there were numerous tiny dots that suddenly appeared out of nowhere like they were magically transported here.

Goblins?

There were Hobgoblins, and Shaman Goblins, leading a horde of thousands and thousands of normal goblins. Their numbers swarmed the map, and all I saw were red like blood leaking on a white canvas. 

Goblins were beginner monsters and weren't a threat, but tens of thousands of them could eliminate a town like this within an hour. 

What's going on here?

Is this an Apocalyptic Event?
