Can someone explain all the iconography to me? Because I don't understand the significance of things like the black star in the double lined half circle the black dots instead of doors, and similar such occurrences. Otherwise this is an incredible resource filled will good ideas and a surprisingly robust generator.
As @GentlemanGames said, these are pretty standard. For example, here is a key from Dyson Logos: link.
- A large semicircle stands for a dais.
- A star in a circle stands for a statue.
- Black dots in place of a door stand for a portcullis ( I treat it as a one-way door).
