Controversial issues and their resolutions.

This situation occurs quite often. There is no other guard near the entrance to the dungeon, except for the one standing at the metro exit. But for some reason, I thought that since there was no other guard, the game must have placed a single guard to protect this entire, so to speak, multi-directional intersection when generating the map. I am not insisting on my point of view. I just want to understand why it is not necessary to defeat the dendroids in the example above.
