Godkiller Rocket Orcs

I've discussed orcs in this setting before, but this is a larger write up on their culture, with goals and adventure hooks.

Background

Orcs are recognized as the most spiritually attuned race, with each orc having a personal connection to at least one god in the heavens.  Unfortunately, this "personal connection" usually takes the form of radio transmissions beamed into their skulls from the god's star as it orbits the earth.  These radio transmissions reverberates among the orc's teeth and can produce anything from voices to an incessant series of numbers. Since their main interactions with the Gods are to be screamed at by them, orcs are generally considered to be hated by the gods. Orcs are highly aware of the location of their god's star in the sky, as the location influences the volume of the transmissions. Orcs are highly regarded as astronomers (the sane ones) and soothsayers (the insane ones).  Orcs are often held up as an example of the damaging effects of extreme religiosity.

Location

Orcs live in the Worthless North, a place of cold winters, shattered settlements and howling void. One thing it has in abundance is spaceship parts.  A huge pile of second and thirdhand steel parts from previous civilizations is the seat of orcish civilization, and all orcs desire to have access to the Spaceship Graveyard.  They need access to the parts to build their own spaceships and go on crusades.

Orcish Crusades 

After years of infighting, tribal warfare and interminable theft/kidnapping of valuable spaceship parts/engineers, one tribe will have enough parts, know-how and rocket fuel to march to the Launch Pad and declare a crusade.  The crusading tribe will build and launch a rocket out of scrap, with the goal of flying into the heavens and killing a god.  Thirteen crusades have been launched so far, with three successful god-kills.  The kill usually takes the form of the spaceship crashing into a random god's star and destroying it, leaving the clerics and followers of that god bereft of spells, divine intervention and spiritual succor.  The orcs still on earth who had a connection to that god find that the voices in their heads are blessedly silent.  (This is why you will occasionally find a sane orc.)  The only exception is the Quiet God's Star, which was long ago reached by orcs yet still remains in the sky.  The First Crusade was lead by Orc-Pope Michael the Unloved against the star of Cyric, the God of Lies.

4 Quests

1. Two competing orcish commando forces are each attempting to kidnap a professor of Engineering from the Academy of Enlightened Thought.

2. A poorly constructed spaceship has crashed into Denethix, with dozens of half dead orcs and their engineer slaves sheltering in the wreckage.  The townsfolk want to kill everyone on board and sell the ship for scrap.  Representatives from the Academy want to kill most of the orcs, save the engineers and take the ship to study. The orcs want to pull their spaceship to the top of a nearby mountain and try a "gravity launch" (pushing it off the top and hoping the boosters are powerful enough to catch the ship before it hits the ground).  The engineers want to get out alive, hopefully without anyone knowing they were ever slaves.  Due to Denethix's complicated legal system, all four have the legal right to do what they desire.

3. An orcish priest dedicated to destroying a god the party hates invites them on a crusade to fly into heaven and kill that god.

4. Orcish regiments stole a large quantity of nuclear rocket fuel from the dinosaur clerics of the northern mountain.  They are moving it to the Worthless North via an ancient train.  The clerics hire the party to steal it back, giving them velociraptor mounts to accomplish their train heist.
