Evernight forest

Danger: Hazardous
Sub zones: Tenebra maze, Luminous hallows
Inhabitants: abyssal slugs, shadow fishes, glophorbias, shadow dryads, night anemones, lightseekers, flash medusas, dusk nymphs, banshees

The trees here have foliage so thick that it plunges the entire area into perpetual darkness. When you enter this zone you wonder whether it's a forest or a cavern... The only sources of light are the glowing vegetation and some very rare and dazzling spots where sunlight manages to breach the forest canopy. Very strange creatures roam this zone and some of the basic laws of physics seem to be altered, making the fauna here especially unpredictable.

Any adventurers who wishes to travel through this forest will need some means of seeing in the dark, such as night vision or infrared goggles, otherwise they won't even see what eats them...

Luminous Hallows

Danger: High
Inhabitants:

Under construction

Tenebra maze

Danger: High
Inhabitants: abyssal slugs, shadow fishes, swallower walls, darkness elementals, negative hydras

This massive temple was once a magnificent palace belonging to an ancient and powerful civilization. Since then it has been overrun by a mysterious force, and the whole place is now shrouded in an absolute and impenetrable darkness.

Unlike in Evernight forest, the darkness here is not natural: it nullifies any source of light, magical or not, and muffles sounds. The only way to see through the darkness is to possess some sort of night vision. It also seems to have a slight resistance, giving the strange feeling that you are moving underwater.

When you enter Tenebra maze, you might wonder whether you are entering a structure or a living organism. The air is incredibly hot and damp; the tortuous halls are covered with viscous fluids and are filled with swallower walls. Over time, some of these walls have grown so much that whole parts of the temple have become alive. Indeed, some tales claim that Tenebra maze itself is alive and has a mind of it's own, and the swallower walls are merely its way of feeding.

The basic laws of physics seem to be even more altered here than in Evernight forest: in some places you can walk on the walls or the ceiling, and gravity can reverse itself seemingly at random.

Aside from the swallower walls, a great many other deadly creatures inhabit the temple. All species present here seem to have evolved in some way, making them more dangerous than those found elsewhere. The most dreaded of all are darkness elementals. There are not many of them, but the particular environment of Tenebra maze makes them extremely powerful. An encounter with them is almost always fatal: a party of adventurers would just find the darkness around them suddenly beginning to solidify, then becoming fleshy, finally turning into a tight stomach...

Their queen Déméchrelle is said to be sleeping deep in the core of the maze, surrounded by an extraordinary treasure, but very little is known about that.
