You have been charged with making a new Origin Story/Class with a mirror for each faction. How do you handle it?

It's your job to create a new SWTOR Class.

Rules of the game:

• Can be either Tech/Force class, or a combination.
• If Republic, the class should have a proper Empire counterpart and vice versa.
• Has to have one origin story per faction, bonus points for also naming their two disciplines.
• The Origin story should follow the timeline of all other Origin stories.
• Bonus points if you outline what their stories are about.

My example:

Jedi Biologist (Beastmaster?) - Sith Alchemist

A "Pet" class, focusing on research and preservation of force imbued beasts in the Jedi case, and the creation and corruption of such by the Sith. Both classes make usage of an animal companion(s) as part of their abilities in addition to their regular companions. Loyal animals you befriend and protect in the Jedi's case, while the Sith is tasked with the creation/corruption of his own twisted little critters.

Naturally, the stories of these two classes would revolve around magical beasts and how to tame them, or in the case of the Sith, force them to do your bidding. The stories will gravitate around working with each factions' research divisions and respective force users both to achieve your goals. Ultimately the Jedi is named Beastmaster of the Order, while (if possible) The Sith ascends onto the Dark Council as the predecessor of Darth Malora, as the head of the sphere of Biotic Science, with the story involving a power vacuum developping in the Sphere as Darth Acharon is killed on Correlia by republic forces.
