The headquarters of Lastwall's government are plain, plainer than the house the party is renting, and a far cry from the great palaces of Taldor or Cheliax or even Razmiran. Lastwall is a place dedicated almost entirely to the service of others, mostly far beyond their borders, and they are not poor, they are simply budgeting. There are, admittedly, people who argue that the impression they leave on foreign dignitaries ought to be a matter of greater concern than it is, but even so this would not extend to impressing the servants of the fake Lawful Evil god of luxury.
The room the meeting is in is in an outer wing of the government building, outside its Forbiddance; Razmir's people are not yet trusted with that password. It is, however, shrouded in a curtain of black mist that anyone reasonably knowledgeable of Golarion's magics would recognize as a Mage's Private Sanctum.
The leader of the other party introduces himself as Ernesto Zampetti, a middle-aged yet still-fit man of probably Andoren ethnicity, judging by his accent, and bald except for his mustache. He gives his title as Chief Undersecretary to the Tribune for Trade and Foreign Affairs, &c &c, and appears to be a Lawful Good cleric, though not a very powerful one. He's flanked by several junior diplomats, but the most notable person on the other side of the table is the red-haired half-elven sorceress who sits unmoving and says nothing through the introductions. Those well-acquainted with the affairs of Lastwall will recognize her as Veena Heilu, Lastwall's Precentor Martial for Magic, which is to say the commander-in-chief of all its military casters, though hardly the most powerful of them.
(Rank and level are largely decorrelated in Lastwall, except at the very top. Whether this is meant to be a lesson in humility or merely because those best suited for leadership are not necessarily those best suited to being powerful combat casters, their Goddess has not said.)
