Night at the the musuem secrets of the sun and moon

Chapter 8

The Doctor and Derpy were enjoying the Sapphire Waterfall on the planet Midnight after they left CHS. The Doctor remembered wanting to come here in a past regeneration but was stuck on the train when a voice stealing entity caused a huge panic and the other passengers almost threw him overboard. The Doctor was grateful this time he could see the waterfall in peace. Usually something bad happens wherever the Doctor goes but just this once he and his companion could enjoy something without the need to save anyone or need to stop some evil entity trying to destroy the universe. Derpy was amazed by how the water turned into solid sapphire as it went down the abyss. As Derpy was watching the process in action several chunks of sapphire flew towards Derpy and landed in front of her. Derpy was happy because it was her lucky day. Derpy showed The doctor what she got and he pointed her to a gift shop near the Train Station and told her they take whatever pieces of sapphire the tourists collect and make jewelery out of them. The doctor gave her a credit bar.

“ Here you are Ms. Hooves pocket money don,t spend it all on sweets,” The doctor said as he remembered using that joke before a long time ago.

Derpy laughed at the Doctor's pun and left for the Gift Shop. While Derpy was away the Doctor received a message on his psychic paper.

“ The darkness is back someone help us,” The message said.

The Doctor ran to find Derpy fast and luckily for him derpy just paid for her souvenir and met up with him. Derpy had her biggest piece of sapphire turned into a necklace with her bubbles engraved onto it. Derpy asked why the Doctor was in such a frantic state. The Doctor told Derpy he received a distress message from someone and he needed to get her before he could go. The Doctor pulled out the key that was around his neck and summoned the TARDIS to their location. The Doctor and Derpy went inside and the Doctor began entering the coordinates from the message and the TARDIS took off. As the TARDIS traveled through the Time Vortex something unexpected happened. The TARDIS began to shake violently.

“ Whats going on why are we shaking?” Derpy asked as she grabbed the railing inside the Console Room.

“ We seem to be experiencing temporal turbulence no big deal it will pass soon,” The Doctor replied as he reached for the stabilizers.

]After the Doctor turned the stabilizers on one of the monitors on the console turned on. The monitor showed that the TARDIS was being pulled somewhere outside their universe. The doctor pulled out his extrapolator and used it to change where the TARDIS would land. After the Doctor change the landing point the recoil of the TARDIS entering another universe knocked both him and Derpy out.

Meanwhile outside the Museum of Equestrian History Larry and the others were decussing who will go after who. Larry and Lyra agreed to go after Tirek since he was the closest to where Nightmare Moon would be. Trixie decided to go after Queen Chrysalis since she and her had a score to settle after she slammed her into a wall twice. And Twilight decided to go after King Sombra since he is going to try and hurt her sister in law and her brother. Just as they were about to set off for their fights a mysterious blue box appeared out of nowhere.

Back inside the TARDIS the Doctor and Derpy manage to regain concionese and noticed that their bodies changed. The Doctor assumed he regenerated because of the dimensional recoil but then he realized this was different. The Doctor transformed into a tan unicorn with a gray curly mane and tail with an hourglass cutie mark with a ring around it. He still had his suit but it was modified so it could fit a pony. Derpy on the other hand turned into a gray pegasus with a blonde mane and tail with seven bubbles as her cutie mark that matched the necklace she bought earlier. The doctor struggled to get up because of his new body. Derpy on the other hand got back up and helped the Doctor get used to walking on all fours. The Doctor checked his screens and could not find where they were. As the doctor kept checking his screens he heard a knock on his door. He opened it and was greeted by a purple pony with wings and a horn.

“ are you ok did anything break?” Twilight asked in a frantic tone.

“ Yes we are fine just a bit disoriented,” replied the Doctor as he tried to stay standing.

The Doctor and Derpy exited the TARDIS and noticed that they were not in their universe anymore. Derpy recognized the mint colored pony among the others. Derpy told Lyra about how Blueblood was executed and how Silver was waiting for her to come home. Lyra was touched to hear Silver was ok. Derpy also said that the portal would be leaving the Museum of Natural History in two days and heading back to CHS. Lyra and Larry were more focused on getting the tablet back now more than ever since the clock was ticking now. The Doctor asked what was going on and Twilight told him everything that happened up to this point. The Doctor knew about the tablet of Akmunrah since he was there when it was re-forged. After hearing the battle plan the Doctor and Derpy agreed to aid Larry and Lyra in there fight with Tirek. Twilight was off to the Crystal Empire to fight Sombra. Twilight did,nt have a plan yet but she would figure one out on the way. Before Twilight could fly off a certain rainbow pegasus pulling a hot air balloon stopped her.

“ Your not fighting King Sombra without us are you Twilight?” Rainbow Dash said as she landed.[

“ You guys flew all this way to help me?” Twilight asked as she shed some liquid pride.

“ Of course darling did you forget how powerful our friendship is,” Rarity replied.

Twilight and her friends set off for the Crystal Empire at twice the speed since Twilight is helping rainbow pull the balloon. Twilight has gotten better at flying by a lot since her fight with tirek she even had enough magic to match rainbows speed. Larry and his team left for the Everfree Forest to fight Tirek. Larry managed to teach the Doctor some of the spells Twilight taught him. The Doctor got levitation down good enough to pull his sonic screwdriver out of his pocket. Trixie left for the Bad Lands to fight Chrysalis. Trixie may be alone but she studied how to fight changelings for moons and this was her chance to apply her studies.

Forty five minutes later Larry and his team reached the entrance to the Everfree Forest. Larry was nervous about fighting a giant centaur that can absorb magic. Lyra assured him he was just a wax statue and was not completely immune to other attacks. Larry and his team made it to a clearing in the Forest that was close to the Castle of the Two Sisters. Tirek was standing on the other side of the clearing ready to fight. Tirek began blasting them with the magic he absorbed on the way. Larry and Lyra created a force field around their team but it barely held off Tirek's attack. Lyra noticed a field of poison joke right behind them and had an idea. Lyra told the others to get away from the flowers behind them. Lyra told them the flowers were poison joke and that they need to lure Tirek into them and he would become weaker. Lyra knew a lot about Equestria since Sunset told her about it. Lyra told Derpy to create a storm cloud and use it to lure Tirek to the poison joke. Derpy found a cloud above the Everfree Forest and grabbed it. Derpy began jumping on it until lightning began to shoot from it. The lightning began to hurt Tirek since his body was made of wax. Tirek ran until Larry and Lyra tripped him with their magic and he fell into the poison joke patch. Tirek began to shriek until he was almost the size of a breezie. The Doctor summoned his TARDIS and went inside to place Tirek inside a jar for safekeeping. With Tirek out of the way Larry and his team proceeded to the Castle of the Two Sisters. Once they got there the place was under a force field. The Doctor pulled out his sonic screwdriver and scanned the barrier blocking their way. The doctor recognized the energy signature as dalek technology. The Doctor also noticed the barrier had six indents resembling a thunderbolt a diamond a balloon an apple a butterfly and a six pointed star. The Doctor said they needed something to open the locks so Larry and his team decided to help Trixie in her fight against Chrysalis. Larry and Lyra were shocked to see how big the inside of the TARDIS was. The Doctor set the coordinates for the Bad Lands.
