AN: I've decided to write a third in the series. I hope you guys enjoy the third (and maybe final, maybe not!) addition to the series!

Chapter 1: Hallowed Grounds

"Player- you won!" Was the first thing I heard as I entered the village. Everything was as I had left it. Except for the fact that the grass was blue- and the sky seemed brighter, and everyone was happier.
"Yes, I did. But before I answer any questions, what's going on here?" I asked quizically.
"When you killed the being, the spirits of light and dark were released. That means that the crimson will be spreading even faster, but now, we have this biome. This is called the hallow. It is the crimson's opposite, and has thankfully ovrerlapped the old patch of crimson, and seems to be bordering every side of our village. That means that we're safe, unless we wander outside the hallow." Dryad explained, glancing around.
"Do we have any allies protecting the borders- you know, so none of the crimson monsters get in.
"Well... we do. Kind of. We have some very, very untame unicorns and hateful pixies. I have dealt with this however, and as long as you keep your distance, they won't attack us. They're kind of like honey bees. As long as you leave them alone, they won't mind you. They will, however, attack any kind of monster from the crimson." Dryad said, smiling at the end.
"Good enough! But I do have a question- where do you think the new patch of crimson is?" I asked, looling around nervously.
"Well... I don't know. I think it's near the dungeon- east of here." Dryad replied, frowning.
I walked into guide's house. It was empty. Strangely, there was no body. No sign he was ever there. Not even a burn mark or blood splatter. I found this slightly strange, but continued to look around the house. Suddenly, I noticed a trap door. I opened it, and looked down. There was a ladder, leading somewhere. The tunnel had obviously been dug recently, as there was still fresh dirt, and I would have noticed it beforehand. I climbed down the ladder, and found a narrow hallway- also recently carved out. I walked to the end, and found a door. It was hastily put together. I opened it. Inside was a small, red, alter. It looked disgusting, with eyes popping off of it, and blood dripping down the sides. On stop lay a curious green sword, and a hastily scrabbled note.
"Player, if you are reading this, I am gone. This also means that you have won, and have aqcuired a hammer that has the power to smash through the mightiest substances. This alter is one of them. I located this when the crimson first apeared, and have been digging a tunnel to it since you fought skeletron. It is a source of crimson, and must be destroyed. But before you do, place all three of your swords in the small slots in the altar. Then it must be destroyed. This will bless your world with a new ore. Any more that you find must be smashed. One day you will clear out the crimson. But first, these must be destroyed.
Sincerely,
Guide.
I froze. I did find a rather curious looking hammer, and took it with me. I pulled it out. But then I remembered Guide's instructions. I located the three empty slots, and put each sword in a slot. The dungeon sword, light's bane, the fiery great sword and the green blade all started to glow. Then, I hit the alter with all my might. In a blinding display of light, it vanished. And on the floor, was a long purple blade- larger than my light's bane that is. It had the same shadowy color. My eyes widened and I stared at the blade in awe. It seemed to hold the power of a thousand suns, and seemed almost sharp to the atom. When I picked the blade up, I felt a surge of power. I almost wanted to drop it, but didn't. It was surprisingly light for its size- in fact, it was only slightly heavier than the blue dungeon sword.
"Now my friends, some of you may have noticed that guide could not be with us, celebrating this day. When I battled the monstrous wall of flesh in the depths of the underworld, guide was killed. His destiny was to be the living sacrifice that summoning this beast called for. Today, I would like you all to honor his death, and remember that I could not get this far without him. I would like you all to remember what he has done for us, and to make sure his death was not in vain. We will purge the crimson, and spread the hallow. We will drive the vile beasts out of our land! And we will not be overcome by the dark times ahead!" I shouted, raising my sword. The whole village had gathered in the middle, to hear what I had to say. Several people cheered, while others only smiled. I did not see one look of disaproval in the crowd.
"How'd I do?" I asked The Dryad later.
"Pretty good. I think the last part was a good touch." She replied.
"Also, without the guide, I will need someone to instruct me. And since you're the most knowlegable one left, I might need your help a bit- particularly on matters concerning the crimson." I said, staring out at the fields of hallow. I knew that the crimson dwelled not to far away.
"I will do what I can, but you have to remember, guide read dictionaries for fun. I suppose I know a bit more about matters concerning the forces of dark and light- for example, I can tell you that Terraria is currently 20 percent hallow, and 13 percent crimson. Good start- but if you don't keep up the good work, that will quickly change." Dryad said with a hint of malice.
"Sounds good to me. In the mean time, how about we attempt to clear out a bit of crimson?" I said enthusiasticaly, reaching for my bag of purifcation powder.
"Sounds good to me. If we ever want to free Terraria of this darkness, we need to get started..." Dryad said, ending on a darkner note. Whatever was to follow, I hoped it would end well.
