A few months ago, I started putting together a Greyhawk campaign set in the Duchy of Tenh. The campaign idea was to have a mix of miniatures wargaming using Ravenfeast as a base and normal RPG sessions using Labyrinth Lord Advanced. I did a bit of work on it and haven't managed to start the campaign, so here's a few assets that someone might fight useful.
I highly recommend the skirmish wargame rules Ravenfeast. Very simple and can be used easily on VTT platforms, like roll20. The book is free as a PDF and at-cost for a physical copy.
I'll update this as I have more assets.
