Ballad of Broken Heroes

In the heart of the Forest of Minuets, there lies a solitary tower simply called "Rendrant". 

The tower is said to stand on top of a gloomy crypt

And its reclusive inhabitants have only ever been seen praying to the forest sigils

And so adventurers brave the winding paths of the forest in hopes of uncovering their secrets

But should they narrowly avoid death and reach the depths underneath Rendrant,

what will be the first thing to break them?

For these thumbnail sketches I was mainly focusing on composition and narrative. 

The group of thumbnails to the left mostly represent the adventurers who attempt to find Rendrant and uncover its secrets. Unfortunately they all meet untimely ends. The group of thumbnails to the right were used to develop the look of the crypt.

My main references for the architecture of Rendrant Keep were late Romanesque for the tower and Rayonnant (decorative gothic) for the crypt. This way the architecture gets more twisted and hostile-looking the deeper we go into the keep. This is also reflected in the color palettes; it starts with golden tones at the peak of Rendrant and progressively gets darker and more desaturated in the depths, with the forest being a middle ground.
