Istredd is bad with strangers but he is somewhat decent when it comes to socializing with people he knows. And especially when they have some very interesting and serious details to discuss. A lot went on during the negotiations so there is plenty to discuss in the aftermath. Istredd recommends his domain since he knows he can shield it and block anyone else from coming near it when he wants to.

Kyle will be able to see that the outside has changed now, the monolith has been replaced with a tower instead. Istredd has not answered anyone as to why that changed.

Istredd leans toward stiff tables and chairs best used for a library, but anyone can create their own chairs in his space. It is mentally intuitive, reacting to the visitor's needs.
