"Ah... as it so happens." Yussa lowers himself before he pulls away. His kaftan flutters as he moves; he still hasn't bothered to button it and he makes no move to do so now as he goes to one of the book cases against the nearest wall.

His fingers hover they pass over books and boxes until he finds what he's looking for. He takes one of the boxes down and flips open the lid. He makes a soft, satisfied sound when he finds what he's looking for. The box is returned to its place. Yussa returns to Caleb and presents a decently sized piece of obsidian, edges rough and potentially sharp given the way it's broken.

"Will this do?" he asks as he lets Caleb take it for inspection. Yussa plucks up a cup from a nearby table and takes a sip of the cold tea in it.
