It seemed as if we fell a long, long way. Now look, where are we? You are breathing too fast, Abra. My eyes are so sore. Everything seems to flare when I look at it. It is the atmosphere of this planet. Rest, I will watch for Zarbi. Are your wings healed? I shall never fly again? No. Why did they make us do this? Why did they make us heap this vegetation into the acid streams? It is the raw material for the carcinome where the Zarbi live. Fed into these pools, it is drawn to the center through underground streams. And as we pour it in, the carcinome grows and reaches out across vortex. What lies at the center? None of us have ever seen it and lived, but we call it the anumus. Do you understand them? No. They are just cattle. They do not have any speech nor motive of their own. Just controlled sentries. We came here to liberate them. It was disaster. Where is Din? The others? We arrived in advance of the spearhead. Our weapons proved useless. They were taken by the Zarbi who were everywhere. The three of us you met in the cave got away with the communicator. But we could not contact our spearhead. When is it due to arrive? Soon. How will you overcome the anumus? With a new invention of our scientists. It has not been tested, but we have placed our faith in the isotope. Doctor, why do not we use the spider as a weapon to get out of here? Because I think we will find it more valuable later, when Ian and Barbara return. Do you think it will be safe? 100%. Oh, no! Use the spider, child! No! Use the spider, child! You delay. Now the child will die. Thus you will learn total obedience. If the child dies, there will be no reason left for me to obey. I have located your enemy. My calculations are complete. You lie. The Minotra are massing on the planet Piktos. Piktos? It appears they are heading straight for Vortis. If you waste time in idle vengeance in face of such an invasion, you will all be annihilated. Where are the Minotra? I have been given peace of mind for a while. I can find out. If it is not too late. Go. Not before the child is released. Go now. First, the child. Doctor, it makes you feel so dizzy. Yes, I know, my dear. I know. Be all right in a minute. Did you tell that thing where the Minotra are going to land? Just about enough for our survival. If I tell them everything, our usefulness will be ended. Now, we've got to get out of here. And I want to find a place to hide this recorder. I don't propose to make them a present at the place of the Jack. There is another panic on by the looks of it. It's no doubt. They've alerted their invasion forces. Be back very quickly on the little information that I gave them. Now, while they're busy, I want you to get back into the ship, find my walking stick and bring it straight back here. Hurry. Some kind of alarm. I hope they haven't found it. We were chased. We fell. They are too simple to understand, Heron. Primitives. What is it you want from us? Petra. We know that from the roof comes hate. The liquid death. Creeping destroyer of we hope there. Yet you stand up right. We will consult the chasm of lights. And if you come from. The. First time you get to the invasion. Just be ahead. Yes, I think so. Tell us what we must do. Nothing yet. Nothing. But we've waited for generations for this moment. And it will come. But a false move and always lost success depended on surprise. If this is an alert. How did they know? Your friends. This man of science, you tell me. Could he be helping them? I'm sure. How can. Do they know? No, what. I'll stay ahead. Plan to land on her side. You can't do just above the crater here to the north. That doesn't mean to say the doctor told them. The zombie must be alerted everywhere, not just here. But this. Will be massacred. But your forces. With useless weapons. Our plan was for an attack on the animals. We would have landed in secret. Overcome this up and destroyed the force that rules them by sheer force of numbers. Suicide on. It would have been suicide to stay where we were. The invasion had to come now. We did not choose the time. It is now. Failure. Will mean failure for all time. The spearhead must be warned. But how. We smashed the signaling equipment. We must get to the top of the platter. Intercept them and warn. Yes, we must. There is a love I can't point it straight at the store. We know I saw 30 or more zombie leaving the crater by the great web. I do not think there will be many more left to guard us. We must try. It only needs one of us to get through. If only we could destroy the love I can. I made her that. You. How. I know that. God, you got it. Now the question is how to make it safe. It's gold. Yes, there's no mistaking it, my dear gold and something more than gold. Gold is the symbol of power of this planet. Which brings me to an incident with Ian and his pen. Ian and his pen. Yes, it flew out of his hand just as he was about to give it to me, a gold pen. Now we have got to find something to realign this power. What? Yes. That is the question. Isn't it? Any sign of him? It's left the love I can. It's our chance to destroy it. Destroy it? Can't we use it ourselves? Only the Zabi can control and fire them. Get ready. Now. Is the gun dead? Yes. I can lead us to the plateau. Come on then, quickly. Have you finished now, doctor? Yes, I think so, my dear. Now we know the TARDIS is the opposing force. The question is which is the stronger. What will happen if you're wrong? What will happen? Well, the astral map will be ruined, of course, but I'm afraid we have no choice. Now just stand back a bit, my dear. Doctor. It was nothing, just a fuse on one of our instruments. The time to complete your findings. Report. It is still incomplete. Excuses. No doubt your creatures told you about the explosion. This is what caused the delay. You must wait. What is it you hold? Oh, nothing, nothing. Merely a piece of damaged equipment that happened. Force on bearing 265. Speed 0.01. We jettison craft at altitude five above crater of needles. Individual descent to SAO plateau, north of the crater. You were in possession of the information all the time. You will be dealt with when the invasion has been repelled. The plateau is just above us. We will remain here until the spearhead arrives. Well, at least we got here in time. You stay on guard here, Helene. The Derby are moving in, surrounding the plateau. We must wait for the spearhead. Then this doctor must have betrayed us. Every creature who invades our domain comes only to prey on us. You are guilty. Throw them in the fire chasm. Will you kill your own kind? This stranger? You are both from that wilderness above ground where the light blinds, the air chokes. Where only destroyer races live. And from where none of us who has gone forth has ever returned. You come foraging into our world only for new victims. Take them. Listen. This wilderness you speak of belongs to you. We are coming in our legions to destroy the dark power and its Zabi slaves. The Zabi? They seized this planet long ago. Enslaved your forebears and mine who remained. They are spreading the poisonous web of the animus to every corner of Bortis. As long as we kill intruders, we are safe. Don't you understand? You are Menoptera. Like this. The Menoptera? You speak of our gods. Your gods. The Menoptera are your kinsmen. Your wings withered on your bodies while you crawled blindly underground like slugs. You were born to the greatest freedom of all creatures. To peace, beauty and light. It is death for us up there. This is not your element. You throw us into the fire. You destroy your own future. Prove what you say. I am Veres Din, a leader of the Menoptera. We come to destroy the dark power who rules this planet. We need your help. They're not here yet. I feel the Zabi are watching quietly. Spearhead. Code word. Electron. Where is your pilot party? Destroyed. Get it off the plateau. Why? Our weapons are useless. The Zabi have our rendezvous. Disperse the spearhead. They will be massacred. It is too late. We are already committed to attack. Look. They are still following us. We try the crater's edge. Come on, hurry. Spearhead. Retreat. We are surrounded. Follow me.
