Gary, the platform is 15 feet higher than the PC's starting area. I'm aware this means the PCs are unlikely to see much of the hierarch unless we assume the jinsul and PCs are both very tall. However, I don't think that should get in the way of things.. if you think it's too much to ignore, move the hierarch closer to the PCs before it start talking if that makes more sense to you.
Mikko, I ran the scenario yesterday (without a lot of opportunity for you to respond prior to running the scenario). We played low tier, barely, with a 7-player party (three 9th level, three 8th level, and a 7th level).
I decided to place the platform 5' high to facilitate the conversation. A 5' platform does make the stairs seem odd. In tier 7-10, I expect the majority of the PCs to have flight capability to easily access the platform.
The PCs decided to try the Stealth route to approach the command center. The 9th level technomancer cast Invisibility on 5 of the 7 PCs. Since the journey only takes 5 minutes, they still had 3-4 minutes remaining on the Invisibility spells.
As a result, the Hierarch only sees two PCs and is quite astonished to see such a small group and insults the PCs. I gave the invisible PCs a round (2 move actions) to move their characters. Then I rolled the Hierarch's perception against the Stealth rolls (including the +20 bonus for invisibility); the Hierarch noticed the PCs presence and that precipitated combat. Sadly, the Hierarch went last in the initiative order and died before getting a chance to act (suffering from 3 operative trick attacks and arcing surge).
