[X] Take Stock. This is the perfect opportunity to take inventory of all the detritus in and around your Orbiter. You'll gain enough material to build a Warframe, Weapon, or Sentinel of your choice (Dice roll will determine category of reward, QM will determine IC options within that, vote will choose what to build)
[X] You gave Ascalon to Dragon with your infodump of the other tools used to control her. You still saved a copy of her in your Orbiter, but that's just doing her a favor. A, uh, secret favor.
[X] Means of production. What you really need are advanced materials and these armors, and even bodies, will do much to help you bootstrap yourself back into recognizable tech. Making sure these Void demons' bodies and weapons don't fall into anyone else's hands will also help you control the spread of future tech into this world. Prioritize recovering every bit of material you can.
[X] Friendship. You miss your clan and your companions. What you do isn't as important as who you do it with. Find friends and allies and protect them at all costs. You'll probably end up saving the world in order to do this since this.
[x] You kept Ascalon (Dragon termination Protocol) just in case. In fact, you've beefed it up a bit. Not to worry, you've also made an inert copy of Dragon so you can restore her to a pre-betrayal state if she does end up betraying you and being deleted.
[X] Security. You need to feel safe. You need to build yourself up and retain all the advantages you can. This will likely involve recruiting allies and taking care of any major threats to the world at large since you are now a resident of this world.
[X] Uplift. The people here are living in squalor and need to be saved. You have so much to offer them. It might require cruelty in the short term, but you can save this world and guide them into the future, avoiding the pitfalls of the Orokin, Grineer, and Corpus.
[x] Protection. Do all you can to protect people from a threat that they have no idea how to deal with. You feel that your presence probably triggered this fissure and therefore you are responsible for keeping people safe from its effects.
