It dawned on me that while I work on my project any maps I make might be useful for fantasy sessions- even before the project's finished and even though the maps may not be the final ones- this one I did when I was building the campaign I'm working on - back then just for Descent - is quite a lovely version of my take on the manor when it was at full glory and not in ruins.
You're welcome to use it for GM'ing any fantasy session you want to set in it, revealing locations only if, and when, PC's first enter them 'fog of war' or in this case 'exploration' style, you can use it as a reference and draw the places out or if you're really ambitious use the actual Descent tiles which is what I'll be doing (although it does eat up some parts of three Manor of Ravens sets- yes I do have three sets, it was the only way I could build my version of the grand manor (I may tweak the final version so there is an option for less enthusiastic players who haven't gone out and got three sets of an expansion because they wanted some duplicate components! Like the fact it makes this manor possible though so it worked really well and I like being able to spring that creative surprise on my players.)
Optionally images on the tiles and the named locations may inspire what's in there and what could happen but you can use them as something different.
If you're using the Descent map tiles then as per the guidance in the Genesys CRB the squares don't really matter unless you need them to as things like distance don't normally matter in Genesys (page 7), however you can make them fit as you need to, perhaps in a simplistic way such as putting characters adjacent if they're interacting at close quarters or making things depicted on the tiles relevant if you so wish.
If anybody else has any useful maps from projects they've made (any style/setting) you could share them here too, maps are good inspirations for and useful toolkit for RPG sessions.
