Elsewhere in the Bonehunters, we learn that Paran gave it in payment to the Trygalle Trade Guild:

She knew more than that, he suspected, but he did not press the issue. Paran made some final adjustments to the saddle, and said, 'Thank you, Ganath, for accompanying us — we would not have survived without you.'

'Perhaps, some day, I can ask of you a favour in return.'

'Agreed.' He drew out a long, cloth-wrapped object that had been strapped to the saddle, carried it over to Karpolan Demesand.

'High Mage,' he said.

The corpulent man looked up. 'Ah, our payment.'

'For services rendered,' Paran said. 'Do you wish me to unwrap it?'

'Hood no, Ganoes Paran — sorcery's the only thing keeping my skull intact right now. Even scabbarded and bundled as that sword now is, I can feel its entropy.'

'Yes, it is an unpleasant weapon,' Paran said.

'In any case, there is yet one more thing to be done.' A gesture from Karpolan and one of the Pardu shareholders came over, collected the otataral sword that had once belonged to Adjunct Lorn. She carried it a short distance, then set it on the ground and backed away. Another shareholder arrived, cradling in his arms a large two-handed mace. He positioned himself over the wrapped weapon, then swung the mace down. And again, and again. Each blow further shattered the otataral blade. Breathing hard, the man stepped back and looked over at Karpolan Demesand.

Who then faced Paran once more. 'Collect your shard, Master of the Deck.'

'Thank you,' the Malazan replied, walking over. Crouching, he pulled aside the cut and battered hide. He stared down at the rust-hued slivers of metal for a half-dozen heartbeats, then selected a shard about the length of his index finger and not much wider. Carefully folding it inside a fragment of hide, he then tucked it into his belt pouch. He straightened and strode back to the High Mage.

Karpolan Demesand sighed, slowly rose from the stool. 'It is time for us to go home.'

'Have a safe journey, High Mage,' Paran said with a bow.
