Totally agree that finding or making a map is challenging! I might consider commissioning one if this proves popular, we'll see.
In the meantime for anyone looking for maps to use in VTTs, I absolutely recommend checking out the various map resources in the #resource-hub channel on Pilot NET (you might need to search or check the pins since there's a lot of information there). If you're already into Lancer, Solstice Rain and Dustgrave both come with maps you can repurpose. Alternatively, Ralf (who wrote Dustgrave and runs Interpoint) has a map generator available here:
