There’s our reversal of the initial situation!
Agon and Torvus were deprived of their energy when the meteor hit, and now they’re the places that have their energy back. The Sanctuary only recently lost its energy (based on the timelines presented by the deceased Luminoth scans, a little over 11 years ago, compared with the more than a century timeline of this war). However, the Sanctuary is a huge and complex area, with tough (and time-consuming) foes. I’m sorry I didn’t get to include the recording at the end of this video: the conversation took too long!
My memories of the Sanctuary, like all places, are associated with my playthrough on Veteran mode. It’s only the penultimate boss that I couldn’t beat, so there’s not much that I didn’t get to see. As such, I recall foes being slightly more of damage sponges than they are in Normal mode, and I probably don’t have to use as many Super Missiles as I am. Nevertheless, the game still gives me just enough missiles that I don’t mind too much how many I’m using. Yes, I don’t want to run out, but I still expect to win even if I do run out. The Light Beam does acceptable damage that that shouldn’t be a huge problem.
