I myself might make an essay on Darth Bane, while not as powerful or skilled in the Dark Side as Palpatine, and not aware f the most secret facets of the Force as Plagueis, his understanding and raw power in the Dark Side of the Force was second only to Palpatine.
Although I must read and reread all three Darth Bane novels and assemble a functional ground to work off of.

Some moar tidbits to later incorporate into da essay,
"Though Vader found Rillao had all the makings of a Jedi healer, Hethrir possessed Darth Sidious' rare talent to cast a dark side shadow over Force users, dulling their abilities." ("Aliens in the Empire, part II")
"The 10 years that followed were tumultuous, but nothing rivaled Hethrir's shock when summoned to the planet Byss to face a miraculously reborn Emperor Palpatine. Hethrir re-pledged his loyalty immediately, coming to understand Palpatine not as a man but as a vessel for the darkness of the universe, an avatar of the dark side itself." ("Aliens in the Empire, part II")
"To grasp the depths and mercurial intents of the dark side, there is no better authority than the Sith architect who brought about its greatest return. Darth Sidious spent decades ruminating on the nature of the dark side, and as Palpatine, he sought to pen the most comprehensive tome on the nature of darkness and the practices of the Sith." ("From the Dark Side Compendium")
In these cantos and the hundreds of thousands that follow, it is apparent that the Emperor has plumbed depths of darkness unknown before. What is known is that the Emperor gathered all the greatest lore of the dark side and collected it. This cost him greatly, as the dark side consumes its servants even as its followers consume each other. ("From the Dark Side Compendium")
