invented to keep out the cold
A language she can understand! And she's starting to get a sense of who this... orc wizard? Maybe? That would be a weird combination, but it probably happens sometimes... is. If she does this just right...
"We may be able to change that, madam. As I understand it, we are the first to have heard the potential for something of value within the tower over there." She nods to the giant statue lighthouse thing. There was a hint of stress on the 'first' there — it sounds unintentional, but it definitely could be a sign they aren't the only ones.
"If there is a purpose to which you would put us, your experience with the area would most certainly be valuable to our interests. If we are the first to get in and back out, well." A gesture with her hands — you know how this goes, don't you? "The secrets within are best sold only once, and most likely not valuable a second time. While your past encounters may not have wished to help you, I believe we can make a deal." She speaks calmly and respectfully, though she does glance to the statue every once in a while. A brief flick of her eyes at the mention of 'past encounters', and a sniff — her disregard for the average human doesn't come through perfectly, but of course she expects no actual thought of mutual benefit from most idiots. Who would?
Unsaid: They are not the only ones here. There's something valuable in the tower, and word got out. If they do their job promptly, they can get back and cut off any other groups from following them. If they are slow, fail, or die, more people will come, and bring with them all the noise and disrespect endemic to adventurers. Tencednil isn't only offering her a deal, she's offering her the best chance to finish this without large groups crowding in. Of course, if she really wants that to work, she will need them to keep quiet about the origin of their discoveries, and to get that she would need to actually ask. Perhaps it would be easier if she spent some actual time talking to them? Tencednil seems to understand how most people aren't worth interacting with, and she might be persuaded to keep quiet about this without too much effort. She seems to understand the value of whispers.
