you walk up to a huge ruin with black ooze covering some of the walls and parts of the floor

you approach the door, avoiding the goo on the floor and go to open the door, but you stop as the door opens for you, you enter and walk around for a while before you spot a figure with their back to you

"you are finally here. And to think I needed to wait a longer time for you to show~ what do you desire~ i can give you anything all you need do is wish it. Come, I would quite like to meet you~"
