Kazimierz had signed his pact with the elf for two reasons. One of the reasons wasn't as necessary, but the second was.
First, he needed a new body. He could've chosen any other carnomancer in the multiverse, but he decided the elf would suffice. Why? That's the second reason. Alkaloth was an experienced, and powerful planeswalker.
Kazimierz was merely the powerful owner of many powerful others. He was new to the spark within him.
He accepted that easily.
He did [i\]not[/i] accept the weakness of requiring another person, however. He only had a minor toleration for it, and that had nearly broken earlier.
[i\]I must temper myself, lest the elf see the joker in my deck...[/i]
He sensed the ambition in Alkaloth almost seconds after meeting him. Driving, singular, and folly. The man believed he could become, by design, a god. He believed he could [i\]rule[/i] the multiverse.
Kazimierz understood ambition.
He also understood the practical and the impractical.
Attempting the rule all that is and ever will be, without any sort of sense as to the grand scale of economic and political power it would take to run such an empire, was, inherently, doomed to fail.
Kazimierz recalled a saying.
[i\]If brute force does not win the day, you did not use enough.[/i]
He knew that was true. On the field of battle.
He stepped to the right side of Alkaloth, glowering casually at the others by his side.
[i\]He styles himself as a dark lord. An 'evil' being.[/i]
But the wraith knew the elf was smarter than that. He likely understood his folly, and maybe even his insanity. Perhaps that was his purpose? To simply [i\]do[/i] what he wanted, because he could? To shake the foundations of the multiverse until the rafters collpased and the inhabitants begged him for mercy and salvation?
[i\]That's why he needs me...[/i]
Kazimierz realized some of the plan, Alkaloth would only be a symbol. A great, omniscient being of immense capabilities, who would be dreaded and hated.
And someone would have to clean up the messes he made, and assure the people of his intentions.
