Warhammer 40k: Secrets of Aurelia and Ambush

After iterating on the Snowed In story line, I came up with the idea of G'mork seeking an human STC.  For those unaware of deep Warhammer 40k lore, an STC is object created during the golden age of humanity to act as a mobile library of all of humanity's knowledge.  It was used for early space colonies who would travel for centuries in space, then land on a distant world and use the ship and STC to build a new settlement.

In this scenario, G'mork is trying to rebuild this STC because they are considered to most invaluable thing in the galaxy.  Access to all of humanity's secrets would give anyone a massive advantage.
