Can I just say, the atlas is bloody great. Setting my groups game in Nibirum and play testing the Temple of Ankun-za adventure tonight and it was good fun. A bit rusty, running a game on Roll20 with the tokens and stuff (which our group prefers over theatre of the mind - FWIW, playing a D100 RPG, not D&D or clone). Makes it very easy, though as a suggestion, having a download of each map as a 70ppi JPEG as well as the Hi-res PNG version would be extremely helpful in situations where you need a map unexpectedly.

Come on mappers, let's get mapping and fill that sucker up!

The 'Darklands" style is going to become my go to, at least for personal projects, I think...

Where are you getting second basement level from? There is the upper fane which is ground level and this subterranean level. As for the roof, the main structure roof is higher and overhangs the internal walls with a triangular-ish bit at the front partially covering the entry hall. All the bits that extrude from the core building have lower pitched roofs that sit under the main roof.

No garden, at least not one large enough to map. Their vittles are provided by the nearby village supplemented by foraging wild root vegetables, fruits and fishing.

I'll be submitting these maps (and a 60 x40 mile regional one) to the atlas (see below).

As usual, the 1st map will require some editing, namely moving the library from the dungeon map to the blank area between the acolytes and priest's chambers and also provided a trap door in the kitchen to access the cool room and of course fixing the key.

The rock background is a much better idea and makes a lot more sense. Shame there is no way to curve the walls using the annual symbols or is there...

Given the amount of work I'm doing, on what started as a simple 'test' map for that annual, I think now, I'll be writing it up as an adventure! But I've got to finish my other one first!

Thanks for the comments and suggestion peeps!

Well, I've spent the evening doing the underground level withpiut really thinking too much and I've made a bit of an error. Given that the sacrificial altar is the circular room, why would anyone, including psychotic, excuse me, devout worshippers, of a frog-like demon/deity bring sacrifices from the upper fane, through their records room to feed the victims soul to their rather unpleasant 'deity'?

Important Lesson: Which is one I always seem to forget; is think about the story of your map, who lives, works, worships there or whatever? And always sketch out your maps first to avoid having to make major edits later, as I will now have to do to the below.

Taking @Wyvern's comments into consideration, the ground level of this complex is done.
