This makes a lot of sense. You can melt the asteroid with reflected sunlight, and then build the O'Neill cylinder inside from the melted material. This lets the asteroid block impacts and radiation so you don't need to build as strong a cylinder wall. Then you can get energy using the same solar mirrors that you hollowed out the asteroid with, using simple Stirling engines to power the generators.

If someone is reading this, I must have failed.

This star "NAJU" was our home, but we were invaded by evil life-forms. Everyone except me was killed.

I am going to try to activate the self–destruct device. If I fail, I would like you to do this task so this cannot happen to any other race. The self–destruct mechanism is protected by a safety device which is located in the underground corridors. Remove each seal and go deep inside NAJU. If you destroy all 10 safety devices, the self–destruct sequence will be activated.

I don't have much time. I hope this message will not be read by anyone… it will mean that I have failed.

Edit: I hope the upvotes are from Guardian Legend fans and not people who think I wrote this.
