Lady Spore's Favor
When guiding Ogron Trevette to ruins in the Northern Lizardfolk tribe, the Lady Spore happened upon a group of bullywugs that had captured a Lizardfolk youth. She overheard him ask for his release as he was Thax, son of Chieftain Grot, but the bullywugs were just that much more enamored about ransoming him. The Lady Spore intervened, offering to repay them with a favor if they released the boy to her. After some additional haggling over gold, which both parties seemed somewhat ignorant over its true value and usage, they acquiesced.
Lady Spore then discovered that this wasn't Thax at all, but Vaszix, who had lied about his lineage to try and escape, unsuccessfully.
