"What do you know of the yuan-ti?
The blue answers your questions.
"Very little, actually." He says honestly and with a shrug. "They are a race of snake-like psionic beings. They have developed several unique psionic powers that may be worth studying, that are not found among any other race."
"We also know that there are three different 'types' of yuan-ti, each more like serpents than the last."
How many? Who's their leader?
"We are uncertain of how many there are. As far as the Greater Council has told us, there are several hundred. The number of the more humanoid yuan-ti - those that you will be dealing with - number a little over one hundred."
"We are not certain of who their leader is. We know that she will greet you once you reach their encampment, though we do not know her name."
Also, will we be getting other escorts than the astral constructs that take us there?
"No, you will not be receiving any aid from the Council, other than that of transportation. It is assumed that you can handle any and all obstacles that you will encounter, if you encounter any at all."
And out of personal interest, how do you make them [the astral constructs] last so long?"
"Every 24 hours, the carriages create a psionic effect that manifests the astral constructs with the metapsionic 'persistent' modification. The new constructs replace the old as the old fade out. The carriages themselves are actually psionic items, developed by a shaper in the service of the Greater Council."
