Erd person POV the battle field
The monsters were about to make contact with the undead army and we they did most of their front lines were run through by the spearmen but many made it through and started fighting as more monster and undead started to fight and the undead the monster fought alongside with started to act strange as they looked around to see their own kind fighting the monsters and then to each other and one of Talions undead warrior walked up to them and held out a hand and they looked at it and took his hand and they were now fighting with Talions army and against the monster and now Talions army increased by 5 thousand but they were still outnumbered but the were holding their ground as they fought and the tide began to turn as the undead and monsters were equal and then the leader of the monster joined the fight and started to destroy undead left and right as the as the scales were now tiping in the monsters favor again and Talion jumped from his vantage point and joined as well equalizing it again.
Talion POV
'I have to find their leader' i thought as we walked through the dead bodies of the battlefield and the undead were protecting we so I could save my energy and I spotted their leader and he was running towards we cutting down the undead around me as I jumped up to dodge his blade.
"Looking for me?" I said and I heard him growl as he charged me when I landed and I frew frostmourne and switched to my warrior armor as our blade collided and the shockwave blast the monster and undead around us away and we started out battle.
Twilight POV
"Can anypony see what is going on?"I asked and every could not see the battle clearly because we were so far away and it wasn't safe to get any closer.
"I'm going to check on the ponies that went through the door." Fluttershy said as she flew away and walked into the door to check on them.
"Well this is fascinating he power here seems to have increased and is only grow since he walked through the door." Discord said as I looked at him and he eyes were binoculars.
"What do you mean?" I asked.
"Well I guess i'll just tell you do you remember when Talion said that this world is ruled by death and darkness." He said and I nodded. "Well somehow he is subconsciously drawing that magic into himself but when he leaves this place all the power he gathered into himself will disappear and return to where it came." He explained and it was very possible since the world was created by his magic and after he finished the ground began to shake and crake appeared on the ground and red magic leaked out of them. "Ah this is a prime example the magic in the ground is be draw towards him but because of the massive amount of magic be moved it is causing tremor and it has only just begun.
"What do you mean?" I asked
"I guess it is similar to my chaos magic but his magic is more violent and destructive chaos only does what is wants and makes everything unpredictably while his magics of darkness and death will do." He went into deep thought a the ground shook again. "Well I don't know what t will do exactly never seen anything like this before." He said shrugging
Talion POV
Why won't you just die." The leader yelled as a fireball out of his sword and I blocked it and I felt the ground shake slightly but I ignored it and keep fighting the undead were overrunning the monsters as they pushed forward and I fought harder as I swung my sword and a wave of ice shoot towards him as his sword lit ablaze and he slicest the ice and the monsters behind him were frozen solid as he charged me again and the ground shook violently knocking us off our feet as it continued and we couldn't get up and the it suddenly stopped and we got up and looked around and the ground burst open not far from the battlefield and a pillar of red magic shoot towards the sky as it stopped and started to form a giant snake and it observed the battlefield almost like it looking and then it saw it as it lunged towards me and I raised my sword but I was to slow and it was too close to defend now and when it touched me I absorbed it and the rest was being pulled out of the ground and absorbed into me and I felt to the ground and I felt normal at first but then I felt a almost uncontrollable mass of power flow into me as I stood up and I was in enormous pain I had never felt this much power before and I couldn't handle it for long so I had to end this quickly and I faced my enemy and he charged again and I focused as much magic as i could into one attack and a large sphere of red magic gathered in my hands as I shoot it at him but instead of the orb moving it shot a massive beam at him and it not only killed the leader of the monster it killed his entire army and I dropped to my knees and one of my undead held my right arm and one the the skeletons that joined us grabbed my left and they helped me up
"Get. Me. Out. Of .Here." I said and I could barely speak and they put me and a stretcher and started to carry me towards the door and the others joined us and they looked worried and discord appeared above me.
"Good show." He said clapping as we walked out we we walked by the ponies that got out and Fluttershy was tending to them as we head for minas morgul and we walked through the gate and the citizen were watching from their homes and the streets as we past and they had worried looks on their faces as we found the hospital were i was put in the emergency room and they looked over me and when they were finished they gave me their finding.
"It seems your body was given more magic than it could handle causing you to collapse and damage was extensive and it has made your magic unstable for them time being and it has numbed your nerves to where it could take days for you to walk again and you magic is very unstable so you won't be able to use it for awhile." The doctor said as he rummaged through his notes.
"So how long for my magic to stabilize?" I asked
"I don't know I have never seen a case like this and you have more magic than anypony I have ever seen o there's no tell when." He said and he left the room.
"Don't worry you be better soon." I heard a feminine and it was almost like it was in my head and I looked around to see no one was here so I thought I was hearing things but it spoke again. "Look at your arm." It said and I saw a snake tattoo on my left arm and it began to move slowly down my arm as it grew in size as it left my arm and became a real snake and it was at full length 15 feet long and it wrapped around the bed and I still couldn't move and it spoke telepathically.
"Don't freak out." The snake said.
"What are you?" I asked.
"Well you could say I'm apart of you" The snake said as it laid its head on my lap. "I was born after you arrived on our world when you first arrived it was only a little but when you summoned the undead army all the magic around the world gathered to you and that much magic can't be sustain in one place without a consciousness same thing with spirits they are masses of magical energy." The snake said.
"So you were the red snake that was made of magic?" I asked.
"Yes and not only was I powering you I was also powering your undead as well making them temporarily stronger." She said.
'That's why I wasn't worried about losing" I thought.
'Yes your subconscious could tell what was going on and calmed you' She said in my head and I face palmed that I forgot we were speaking telepathically. 'So after the battle and you collapsed I was bonded to you and that why I didn't disappear like the magic you were given and I have my own magic as well' she told me.
'You said I was going to get better so what do you mean?' I asked
"When I am fully bonded t you like when I was a tattoo on your arm I can manage your power and magic so I can heal you from the inside and stabilize your magic so it should only take a day or two for you to get better but you should sleep or now and rest so i can work.' she said and she put her head on my arm and she was sucked in and she looked at me and winked then went still as I closed my eyes and went to sleep
