Hunt down the theives

After having situated the man, you decide that justice shall be delivered onto the thieves who attacked the man. You know exactly where to start. With an esper. Espers are renowned for their coy ways. Knowing things nigh impossible to them. Making your way through town, you come to your destination. Tucked deep into the rotting district of town, dwells an esper shop. A quaint store, its exterior in near shambles. All of its windows draped in chartreuse tapestries.

You trip a bell entering through the doorway. Its small chime sounds off into the small room. To the left, a few shelves sit. Each one full of eye-catching items. To the right, a large rectangular ornate rug occupies most of the floor. A few wooden chairs sit around it. Straight ahead is a small counter. There's a small potted plant, a carnation. Its petals are no single color and almost appear to be shifting between many colors. There's a doorway to the left behind the counter. Out of comes rushing a noir skinned man. An elegantly shimmering emerald dress is draped around him. His figure was nimble as he strode in. His skin was a tawny rose color, extremely supple in appearance. Once reaching the desk he addressed you with a smile, "Greetings, esteemed patron. We don't many knight 'round these parts. What a chivalrous cause thst brings you here Ser Knight, or should do you prefer Ser L--"

You quickly interject with a clearing of your throat "Ahem, 'Ser Knight' will suffice." There's a moment of silence, "Can you help me find the bastards?"

"Of course. Before we begin, I, unfortunately, must discuss payment." The esper plays with the jewels hanging from his sleeves.

"What is the cost?" You ask ready to pay.

He smirks, "What do have to offer?"
