This was a commission piece I did, and yes, it is star wars fanart, so It is a public post and not a paid for post. These are two original characters, getting it on in a Sith tomb on Yavin IV or Korriban that is still to be determined. The rest is going to be a bit nerdy, so if you're not into the Star Wars Expanded universe, it may go right over your head.

 On the bottom you have Aleema she is from the Imperial Era and belongs to a friend of mine (This is his DeviantArt page if you like SW Fanfiction go check out his page), she is a force sensitive and quite adept and catches the eye of Emperor Palpatine. She becomes the Hand of the Emperor in her main story arc. In this offshoot/Alternate story, She follows a set of rituals and texts to a sealed chamber on Yavin IV, and finds Jen'Ari, my Sith Warrior once Wrath of Emperor Vitiate, turned Wrath of the Empire then Empress of the Eternal Alliance who was imprisoned in Stasis. She frees her only to realize too late who she is and how powerful she is. 

When the Emperor finds out, he tells Aleema to kill Jen'Ari before she can regain her strength. This goes bad for Aleema and they begin a very tantalizing cat-and-mouse relationship, which may very well end in this scene here:

Aleema wants more power and has decided to take it from Jen'Ari through a ritual, but halfway through, Jen'Ari, having realized what was going no flips the tables and drains Aleema of her power, leaving her either dead, on the brink of, or powerless. That is also still to be determined. I may even write up a few scenes between them and post them. 

I have also included a picture I made of the pair from a scene earlier in their relationship as well just after Palpatine tells Aleema to kill Jen'Ari. For anyone wondering, Aleema is 5'5" sans the heels she's wearing and Jen'Ari is 6'3" sans heels.
