This arena is essentially a tightly compacted jungle/forest, with tall cliffs along the edges of the arena
At various points in the forest/jungle there are some small waterfalls and ponds
The arena is open to the sky and elements, however due to the tightly compacted nature of the jungle/forest, there are areas where the sky cannot be seen, along with lots of shadows and places to hide
At the centre of the arena (jungle/forest), there is a medium sized temple, it is the darkest at this point and there are pyres, full of fire and wood, at the entrance to the temple. The fire that burns within the pyres can not be extinguished, but if the fire is removed from the pyres, it can then be put out.
Inside the temple are various Greek statues, roughly 6 feet tall
There are numerous and various species of wildlife hidden amongst the forest/jungle, but none larger than a grizzly bear
