I had Glynn from Monkeyblood Design turn my home drawn campaign maps into something much more impressive and I thought I'd share the results here in case others might be keen on doing so. Unfortunately, I can't seem to upload the files here due to their size, but Glynn posted the results on his blog: https://monkeyblooddesign.co.uk/2020/10/25/krysonia-leng-commission/
They are the Krysonia & Leng Commission, posted on October 25. I think he did a great job, as always.
What I've done in my campaign is situate Hyperborea at the North Pole. One can sail there, use gates in the ruins of Sarkomand in Leng, or travel via the Cyclopean Deeps into Underborea. But you should be able to spot other references to weird fantasy, classic modules and classic rock in some of the place names herein.
