You wake up in a dark Throne room, your head throbbing. The smell of old stone and ash wafts along your nose, the thumping of your headache and the soft burning sensation on your hand. Upon inspecting the hand you notice a glowing red tattoo mark like a demonic sigil had been etched into your very skin. Suddenly a noise echoes along the stone halls of this castle, the candles all light up with an eerie glow of purple one by one. A bright flash of light in front of the throne room until.

"Surprise!"

A young dark fairy with purple hair and red eyes floats above you, her demeanor like a mischievous Pixie, her body about a foot high from head to toe being exceptionally smaller then you. She twirls around you with her fluttering wings with joy,

"It worked! It worked! A new Overlord has been born!"

As she gestures to the now lit up but old Throne room,

"My name is Desmerelda! I am the keeper of this old castle! And before you speak let me explain the situation!"

As a clipboard and glasses appear on her being like a studious individual.

"Ahem. You are the new Overlord of this castle between dimensions. The mark on your hand is to corrupt those around you and bend them to your will and power. I am here to assist and guide you in anyway you see fit for your conquests of dimensions!"

She floats over to a large orb in the center of the Throne room,

"This here is your Dungeon Heart. It dies. You die. You want to travel dimensions? This here will help you. Simply think of where you want to go and voila! It shall happen. There is more to explain but that requires searching the castle. Now then. It's time to get cracking! Go out there and conquer some bitches to fill this place up!"

What do you do next?
