Select "Democratus Surface", then "Ballotine/Doren/Whitendon" in that order to go the Whitendon map. Once there, open the console window and type invoke 87:3035. There will be a dialogue -- click through it, and receive a cobalt crawler. Repeat it another seven times to get the eight needed to assemble Hecatomb, the game's most powerful Mystech.

To get flower petals to upgrade your Beetles in the Elementor window without having to exit and reenter the area you found one in, or wait for it to regenerate, open the console window and type invoke 30:2000. You can keep doing this as many times as needed with a regeneration time of a few seconds, as long as you are in an area where there actually is a lifeflower
