INTERLUDE: KLEBORN WAKES UP...
The blast from the ghostly figure's spell renders you unconscious; you awaken, to find yourself in a cage which is comprised entirely of magical energy. The cage is located in the Northern section of a large, circular room, which must be a tower, from your reckoning. There is a staircase in the Southern section, and there is a window on the Eastern facing. You are wearing your normal clothes, but you have been stripped of your armor, weapons, and other equipment.
There are three, wide, long tables arranged oddly in the center of the room; these tables are covered in vials, bottles, books, tools, parchment, and miscellaneous pieces of junk. Your gear is on the Southern-most table, piled haphazardly in a heap. There are two, large areas of the room that look like they have been burned recently, perhaps by explosions caused by fire spells. In the Western section of the room, there are three, runic circles, labeled:
PA PR FU
Two of the three circles (PR, and FU) look badly scarred and burned, and some of the runes are blemished and smudged. However, the circle labeled PA looks to be perfect and un-touched.

By one of the tables, an elderly man of
Wolf Nomad descent, his hair woven into two braids, wearing a simple, brown, vest, a plain, white, cotton shirt, and a rune-covered sash that hangs on his left shoulder, stands scratching his chin, as if wondering which thing to pick up from the table. Without turning to look at you, he says:

"I don't know who you are, or how you got here, but your arrival was just the distraction I needed to overcome my treacherous apprentice and his little Elf girlfriend. I thank you for that. Look at the mess they've made of my lab. It's fortunate that the tables were warded against fire, or the whole room would have been blown sky high. Sorry about the cage, but until I discover whether you are friend or foe, I cannot risk letting you roam free. While you remain within the cage, the magic of it will prevent you from being hungry or thirsty, or needing to relieve yourself. It makes keeping prisoners a maintenance-free endeavor. Two of my teleportation circles have been ruined by the spells that were cast, and I will need to repair them. I will be gone for a time. When I return, I will attempt to use my magicks to determine who you are, and what your purpose here is. In the interim, feel free to twiddle your thumbs, whistle a tune, daydream, or anything else you can think of to entertain yourself. Adieu."
And with that, the elderly man walks downstairs, his footsteps growing more and more faint, the further down he goes. Finally, you do not hear him at all.
