I can't figure out what the red arrows are. My best guess is that they indicate the direction that the map was distorted in that area. It would be good if somebody would explain.

First! Can't believe I'm north! King Pando (talk) 03:34, 14 February 2026 (UTC)
- What do you mean that you're north? This isn't a good name (talk) 03:42, 14 February 2026 (UTC)
- You’re north, I’m fourth :) Logalex8369 (talk) 04:53, 14 February 2026 (UTC)
