Blink

Starian, the kingdom of the elves.

Hardon, the village of the orcs.

And finally,

Solus, the city of the humans.

Walls cover the boundaries of each. Dwellers are afraid of each other. Rulers want to end each other's lives so they can expand territory. Amongst the elves, orcs and humans, a group of strange creatures that somewhat resemble an elf with the wings of a pixie and the battle instincts of orcs live.

They are the Blinks. Not only are they important in keeping the balance, but because they are the also the Keepers of the Crystal. This Crystal is what keeps everything alive. Without it the whole planet of Terraria will fall into darkness.

Now a fight amongst the elves and humans awoke the mighty Sulu, an evil warrior who wants the Crystal under his possession to wipe the whole existence of Terraria. What he didn't know is that the Crystal is actually a whole Blink itself.
