Philip chose to turn into the famous Rasputin.

"Could you be Grigori Rasputin?" Ekaterina asked in Alexander's excited voice.

"Yeah! You got it right!" Philip said with a chuckle.

"It's so strange to see such character without his famous beard." The transformed woman commented while caressing Alexander's perfect chin. "I almost couldn't recognize you."

"I mean... the beard is still here, but I just decided to trim it a bit." Philip answered pointing at his bushy chin.

"Hmm. I do agree that it would've been rather unsightly for today's standards." The woman said, probably thinking on all those black & white photos of the Russian mystic.

"I refuse to believe that he looked alright even for 1900s standards." The boy shook his head with a smirk.

Ekaterina chuckled at that.

"Well, all those noble ladies who gladly accepted his 'favors' might disagree with you, Mr. Connoly." She said with a sagacious smile. "Speaking of which, is it true what they say about his... endowments?"

Ekaterina made a gesture with her eyes while staring at Philip's downsides, and the boy knew immediately what she was referring to.

Philip shuffled uncomfortably and covered his crotch with Rasputin's calloused hands.

"C-Can't that wait until later?" Philip asked in a deep but hesitant voice while staring at the door.

The woman laughed once again.

"Haahhh... I almost forgot you're only 19..." She said with a complacent smile. "Sure, Mr. Connoly, you can come in."

She opened the door and invited him in.

"I'll meet you in a while to exchange more pleasantries." She winked at the boy, making the gesture incredibly odd since it came from the body of the famous Alexander. "Meanwhile, please enjoy the party. We've planned a few events to make your stay one you'll never forget."

As Philip entered the hall, he adjusted his clothes yet again while thinking about Ekaterina's last question and the rumors regarding Rasputin's nether region.
Well, by now Philip knew for certain that those weren't just rumors.
After all, he could feel it at all times, constantly rubbing his leg on every step and making Philip regret not buying new trunks after he transformed, something to better accomodate his new size.

It would've been useful if his powers allowed him to shapeshift individual parts of his body to better adjust his proportions, but that's not how his powers worked. Turns out that every individual who was alive or had lived in this world left some kind of magical imprint which remained for an indefinite ammount of time even after their ****.
What Philip did was looking for that exact imprint by calling the person's name. And once he got a hold of it, it only took a few hours of focus to turn into that person, acquiring his/her exact shape and all of their features down to every wrinkle and freckle until Philip became an exact copy of his chosen objective.

It was a long and draining process which lacked versatility, since he couldn't make any modifications to his new body, and his form was limited to how his objective looked during his prime. Therefore, he had become a version of Rasputin which was slightly younger than that of his photos from later days.
However, he knew that his limitations were due to his inexperience, and the boy looked forward to become like other shapeshifters who could actually perform all sorts of crazy changes in their bodies after years of practice.

After a short walk, Philip finally entered the main venue, and was immediately flabbergasted by both the luxury and the ammount of extravagant individuals filling the hall. It wasn't that many of them though, just 3 dozens or so; but every single one of those figures had an undeniable presence that seemed to carry their own weight within this great room, and Philip found himself absorbed by their looks and gestures. He had been a History nerd his whole life, and he quickly started to identify some of them mostly due to the fact that a lot of the guests had opted to dress accordingly to the historical figure they had chosen. This was, quite literally, the greatest cosplay convention in all of History.

And Philip was now a part of it.

The boy gawked at the sight of Jane Austen casually conversing with a fierce-looking steppe man who might have been Attila the Hun, then laughed incredulously when he spotted the figure of Voltaire next to a table stuffing himself with spicy chicken wings. Wasn't he a vegetarian?! There was also Takeda Shingen shaking hands with Catherine the Great and the deep musical voice he heard from his right was none other than the fucking Julius Caesar singing a pop song with a microphone and a karaoke while being cheered on by several women of different origins, one of which looked suspiciously like Isabella of Castille.

The whole venue was full of these characters from all over the world and all moments of History intermingling with each other, and Philip still couldn't believe his eyes, so he kept gawking at the whole picture like an idiot until a mellow feminine voice greeted him from behind.

"Wait, is that Rasputin?" The woman asked, and Philip turned around in surprise to see a beautiful lady of delicate features and caramel skin dressed as some kind of Egyptian queen.

Philip recognized her almost immediately, and couldn't believe his eyes.

"Queen Hatshepsut?!" He asked louder than he pretended.

The aforementioned stopped in her tracks with her mouth open in a big 'O'.

"No fucking way!!" She happily exclaimed. "Finally, some cultured people around these parts!"

She jumped forward and gave Philip a very unexpected high five. Then made a wide gesture with her extended hand, pointing at the whole venue.

"Can you imagine that almost none of these morons managed to recognize me?! They keep calling me Cleopatra this and Cleopatra that! Always mistaking me with that Greek wench! At this point, I believe I should just hang a big poster around my neck with 'my' name written on it!"

"That wouldn't make any difference though." Philip said with a very serious voice. "I don't think any of them can read hieroglyphs."

The person transformed into Hatshepsut immediately started howling in a laughter so contagious that Philip immediately found himself laughing almost as loudly as she was. And they couldn't stop for a long while.

"Haahhh... I'm so fucking dead." The woman said while wiping a tear.

"Should we start mumiffying you then?" Another person joined the conversation.
