I wrote this up for a private chat but now for time management i reuse it here for this post:
This was my first map, so there was now intentional plan, but it developed in the mapping flow and so came possible ideas about the setting.
Generally i imagine the scene as a once great city (with possible important treasure) that got swallowed by the nature (earth and roots).
Markers on the map.
1 - my intended starting point, though could be used as cave entry to enter the mud mountain and ruins
2 - alternative starting point, or possible exit point.
3 - root object can be destroyed and then the ruins are accessible via teleport spell.
4 - dynamic object (rubble) can be destroyed to access ruins via teleport.
5 - hidden platform behind the waterfall (camera is a mess as generally not polished yet in the level)
6 - possible this i called eagle rock and i imagined a nature people with wings (winged elves maybe) living there. Possible to join forces with these against the undead in the ruins. Possible plot to find out that they were responsible (or had a part) for the destruction of the city. (i imagined even possible taking (moral) sides with either the "elves" or the "undead".
Imagined a nature elf lair level inside the cave connected to the fallen river. (still to do this level but lacking the time and maybe i would like to do some entirely different map.
7 - possible encounter with archers, zombies crawlers poison
8 - possible encounter, here could be realized that the city was swallowed by roots and earth.
9 - possible encounter recommended with archer and poison. I imagined the tree coming out of the wall as a possible entry into the mud ruins. If allied with the eagle rock faction, they could help here in a battle or vice versa.
10 - this actually is the most unsure part of the map and i though even to delete it. Imagined this as the cage for monsters and abnormal creatures of the once big city. Maybe this decadence finally brought the rage of the nature and the city's fall.
As i said i builded this area with the flow and therefore sometimes it is hard to redo or delete some parts of it. But i bet by changing certain things and also radically delete some parts (10) and create some new could certainly improve the map.
