Where does “Edenic” come from?

I need to clarify the chain provided. It shows "English Eden" at the beginning, then jumps to French "-ique," Latin "-icus," and PIE "-kos" repeated three times. This appears to be a suffix chain rather than a complete etymological path for "Edenic." However, I notice the instructions say "State only what the chain supports. Do not invent dates, cognates, or intermediate steps." The chain as given doesn't clearly support a coherent etymology for "Edenic" as a whole word—it seems to show only the "-ic" suffix derivation. Based on what the chain actually supports: Edenic is formed from English Eden with the adjectival suffix -ic, which derives from French -ique, Latin -icus, and ultimately Proto-Indo-European -kos.
