@BCTheEntity I am aware of the fact that nobody has yet introduced the lizardman to the reason why our party is out there. In fact, it's the very point of my post.
If it were in any way achievable, I am sure your assistance would be of great help to our small-yet-tight-knit band of adventurers; but alas, I am also quite sure you shall in the future be occupied with more pressing concerns than our own..
An-Hasst however knows why the party is out there, because he's a part of it and has received the queen's instructions as well. Yet Sett states to the unknowing lizardman that he will likely be occupied with more pressing concerns than theirs ? What can be more pressing than a world-saving quest ?
An-Hasst is just amused because this discrepancy between what really is and what Sett says is an indication that he's not straightforward in his speech, which the Skayleigh assumes one would be if there wasn't any hidden intention behind. Which one that is, however, he doesn't know yet.
