If history is always doomed to repeat itself, is the illusion of choice futile? Is change even an actual possibility? Why even attempt to choose if the end result is the same as to not choose at all? Perhaps to not choose is a choice.
These are the ideas Sombra mused while he watched Trixie being frantically chased by six, no seven golems.
"Ahhh! It didn't work! It did not work!" Trixie cried, one golem nearly crushing her with it's granite arm. Sombra chuckled darkly.
"It might have actually worked if you had any form of competence in the subject of magic." Sombra laughed, "Alright, good thing theres more then one way to break a golem. Look for it's key stone."
Trixie was barely listening, as she was half way up a tree. The small horde of rock monsters had gathered at the base of the tree, clawing at the trunk.
"Why aren't they trying to get you?!" Trixie exclaimed. Sombra shrugged.
"I know a thing or two about this kind of thing. They won't attack unless provoked. In their mind I'm invisible as long as they don't perceive me as a threat. Now as I was saying. Pull out their key stone. It's the single rock that holds them together. Their heart if you will." The Dark King explained. He trotted forwards, approaching a golem. Examining it's midsection which consisted of swirling rocks held up by red, green and purple magic, he reached in, and pulled out a seemingly insignificant pebble. The golem shuddered for a moment, and Sombra stepped back as the golem colapsed into a pile of rubble.
"Heh, see? Simple." Sombra smiled. His smile slipped as two of the golems turned to face him. Sombra backed up a few steps. "Heh. Well that's not good."
He thought for a moment about simply leaving. He could simple walk away, never see this accursed farm again, and nopony would have to know. Then he looked up at Trixie, barely gripping to a branch as the golems below shook the ground below, demanding her doom. Sombra...He just couldn't leave her there.
Closing his eyes and swearing unmentionable things in an old dead language, he charged the golems. They ran to meet him. With a spin, Sombra launched his large sombrero at the golem to his left, it didn't exactly do anything, but it drew the attention away from him as he quickly ripped the keystone from the belly of the golem to his right. While it was still clawing at the air, he shoved it's keystone into the other golem.
Without going too deep into the history theoretical magic, Starswirl the Bearded was the first to record that all entities that have a grasp of magic in fact have a unique signature in their mana essence. When a foreign magical source interacts with another magical source, any number of effects happen.
In the case of a golem that has another golem's keystone inside of it? The magical reaction can be rather violent.
The golem blew apart. Bits of rock flew everywhere as Sombra stood there, his face calm, his eyes fixed on the other four golems. They were weary now. They had witnessed three of their brothers fall to this pony. They grouped together, and waited for him to make the first move. He did not hesitate.
Slamming into one with his shoulder, Sombra winced. Still, as the monster recoiled he pulled out it's stony heart and it crumpled to the ground. Running up and inserting it into another, he bucked the beast in the chest, sending it stumbling backwards, crashing into the other golem.
It detonated, taking it's companion with it into oblivion. One left.
Sombra stared at it, and it stared back. Both waited for the other to strike first. A single mistake could be fatal. Sombra blinked and the rock monster was upon him. It's hard claws dug into his side as rock met flesh. The dark pony was flung back, but the golem collapsed. Sombra clutched it's keystone in his hoof.
Maybe I'm not so terrible after all...or some...thing...I... Sombra thought. The world spun and he struggled to stand. His own hooves couldn't hold him and he collapsed, the light fading from his eyes.

Sweet Celestia. I figured he would get rid them rock things, but I didn't want him dying over it! A voice echoed through the empty black.
What...? Where am.....Who?
I can't believe this. You prodded him into doing that Igneous. Another voice, much more feminine, motherly sounding.
I...um...hello? Sombra called out from the void. Nopony called back.
Sombra...he saved me. He died to save me. Yet another voice.
Hey...that's Trixie! Wait, died? I died? Sombra felt something move in the darkness. Like it folded in on itself. Princess Celestia stood there, in the fold, her face impassive.
"Well it appears you somehow managed to do some good in this world." Celestia muttered, "Still, your not quite done yet. You shall not welcome death this time."
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Sombra did not awake with a gasp. He was not miraculously better either, but a twitch of movement stretched across his otherwise dead face. A wince of pain.
Trixie gasped. "He's started breathing again!"
"Impossible..." Igneous whispered.
The once dead pony laying on the couch was now seemingly quite lively, and started coughing rather violently, and was flailing about in an attempt to get up.
"Gosh darn it hold him down or he'll manage to hurt himself further!" Igneous commanded. Trixie part tackle part hugged Sombra until he stopped panicking. Even afterwards, she continued to hold on to him.
"You did it. You really did it." She said with a smile.
