First of all, this mission is not a serious suggestion. It is the final and the most annoying mission in a series of annoying missions but it gives a reward of 12 very interesting artifacts.

Asphodelian Skies

Mission Briefing
We've witness many type I civilizations perish through their own designs but one of such catastrophes we've seen stands out. Our scientists have spent innumerable hours studying how to recreate that particular phenomenon which gave very enticing results. What better way to culminate your vision than to unleash it in our enemies. We trust, in the end it will be worth the effort.

Requirements: rank 300+, 20 disables, 20 planetary invasions, 20 enemy kills, 100 NPC kills

This mission will end after being completed once. 75 rounds.
Per Round Requirements: 1 scientist (1 scientist is killed every round), 100 energy, 1 Prejoran Tech, 1 XTS-9, 10 complex tech parts, 1K research points, 10M Credits, 1 errant disfavor (dropped by Errant Asphodel Pilgrims - NPCs that randomly appear while this mission is active)

[Note: The Errant Asphodel Pilgrims are lost ships still trying to find that non-existent planet called Asphodel. The ships keep running around in that orbit where the planet used to be but all their crew have been dead a long time ago from malevolent phenomena called Pandorum Syndrome that affects both android and biological crew members.]

You posted this as a joke, but I would like you to hear my feedback none the less:
The background behind this I definitely think could be made into its own storyline. If you make the mission chain long enough you can go FTW with the end-game rewards. In fact, with your permission I would like to make it for you.

I will call it the Pandorum Saga!

As a saga maker, I would like to see this made into a saga myself. As for the mission...yeah...way too hard, even for the highest ranked people.
