The Glass Castle-
The arena setting is an old ruined castle, once belonging to a race known as the Eternal Dreamers, sitting upon a nexus point in the multiverse. The castle is situated on a mountain range, roughly 4,000 feet above sea level. Above the castle the skies are a pitch black with a myriad of stars and borealis effects that cascades an electrical glow upon the castle creating a surreal lighting pattern. It is rumored that the castle allows entry to the realm of the Dreamers themselves. Although why any would venture there is the question.
The glass walls are anywhere from 30-40 feet thick around the base of the castle, becoming thinner as the walls rise. The walls themselves are roughly 50 feet tall and the four towers; one at each corner is 75 feet tall.
The fighting area: The actual area that the combat takes place in is the entire castle. The castle although made of a type of glass, is not transparent; rather the glass is an incredibly dense material that resists damage. There are walk ways roughly 20-30 feet above ground as well as the tower structures themselves. The ambient temperature is 29 degrees throughout the castle.
Once the fighters enter the ruins, one atop the North-Eastern tower and the other at the South-Western tower at the top, the ruins change. The fighters realize they are no longer alone, each can see the other in a shimmering green light.
They will also see a skeletal being in dark armor lurking just on the periphery of their vision. This being will not interfere and any attempts to make contact will result in nothing. However the persistent feeling of being watched abounds.
SPECIAL: In the throne room on the second floor, is an ornate staff made of glass similar to the walls. The staff when grasped creates a shimmering image of a skeletal woman who speaks several words and when done the weapon that is the primary weapon of the person grasping glows with amber light. This lasts for 6 total posts and allows the person wielding such a weapon to open the glass walls as if a door were there. The walls seal up immediately after the user steps through.
As usual I want a good clean fight. Make it entertaining and try and work out any minor issues on your own. If you need me to intervene I will need all pertinent posts and sections.
