Zel will probably suggest that Heojin's idea is a good compromise, mostly because he likes him. He'll also agree with Wan that anything tainted should be sealed off and avoided. He'd also suggest they leave the library alone, once they check it for traps. A public library is a good thing, and whatever scholars on the shell would appreciate it. He's got enough magic and experience to be useful for construction

Iroh would suggest they not demolish the palace, but open it to the kedan as well. And leave some of the main rooms untouched for historical purposes and to make it clear that things like the throne room are not being used by the Foreigners. And perhaps some of the larger rooms and gardens could be turned into public spaces. Even if they do decide to demolish the palace, he'll suggest leaving the main rooms as a museum for the city's residents.

Tazendra doesn't really care, but she can help with demolishing things and would also suggest removing the nice things (art, textiles, books, sculptures.)
