The rank 2 Metal Hand's tome had been sitting in Liam's ring, so Grace had offered the Roaring Thunder Sect a trade after worries about scams became nothing more than a distant memory.
Yet, goodwill or not, the Roaring Thunder Sect was a far superior party compared to Liam and Grace. Any trade had to end in the Sect's benefit, or they simply wouldn't happen.
