Question of interest (Patreon)

Hey, this is a strange question, but I know there are several DnD layers and DMs around my following, so... Do you know any good map design software?

When I resume the schedule, I do want to make that "Aya" short comic, but for it I'd also like to have a map of Sinae!

... The problem is that I kinda suck at drawing maps lolz.

So if anyone knows a good software, please throw me a link!
