Some Questions

Please can we find out when services are likely to be held in the main temple - ie do they have a standard schedule of matins, compline etc? And what is the order of service? We are wondering if there are times during a service when the High Preist (ie Sorlor) is likely to be alone in the preparation area. Where would her non-ecclesiastical attendants (ie Hentron) be while she officiates?
They do have a schedule, but it is running a "skeleton service" at the moment (pun intended). It is highly likely that Sorlor will be attended while she officiates (even if only by someone keep the illusions up and running!)
You gave us the list of Elite rogue toys, and we already have the 'Junior' level of rogue toys. Is there a 'Senior' level of toys to be bought? Actually no! 
To ask Thirson:
Ghassan specifically left three items for us: The scrying circle,	the goblet, and the (blank) book of enchanting.	(https://get-the-gelf.fandom.com/wiki/Zoom_2022-01-11_21:00).	The first two were obviously critical items - so we might assume	that the enchanting book is also very important. Does Thirson know	what that was for, or any prophesy related to it? We also left	SwanFeather's holy symbol as we respectfully didn't loot her body.	Was that a key item?
Thirson acknowledges that Ghassan probably thought the book was important - but personally has no knowledge of it.
He would assume the Holy Symbol was not a key item 
Tell us more about the Blue order - Joshua tried to intimate that we	knew he was an agent of the Blue Tower in the initial conversation,	and I'm sure this can be made clear to Thirson without Joshua having	to actually say it. We would like to know what the various Blue	offices are, and where they are located. What their connection is	with Wyldwood (who seem to want us to help them) and with the	Twisted Ladder (whose windows seem to lead to them). Perhaps he	could complete the list below?
The "Blue Order" is not really a formal organisation, the individuals involved have no ties to each other, nor are they affiliated with Wyldwood. Individuals who effectively provide an exemplar in certain trades/aspects become known as members of the Blue and tend to adopt the colour as a badge. All of the aspects known are based around organisation, which would make the members natural enemies of the self styled Chaos faction (in fact Thirson sees the Chaos faction as just an invention of Toscin's that he uses as a way of self aggrandisement). Strangely enough though, the Twisted Ladder does seem to strongly align with the "Blue Order" and perhaps it is no coincidence that the base of the ladder (if you climb down internally lies so close to Toscin's other "half") 
Given the regeneration of Blue title holders when they die, the Blue	Order must have known than Hentron was still alive - as a new Blue	King wasn't reborn. So who else knew?
Not all the Blue member reincarnate, in fact the Witch is the only one that does. The Blue Tower reforms when its occupant is ready to take on the role - but he/she will be a totally different person to the old Blue Mage for instance 
Given our experience of the Blue Witch's rebirth, are there any	precautions we should take when Hentron is re-empowered? (Just in	case his immediate first reaction is to say 'Hi guys, I'm your King'	- and he's a walking rod of rulership.
Again, the Blue Witch is a special, very tied to her area - with a very specific and narrow role.
What about Sallahan? 
Sallahan is where Toscin used to make his headquarters, before his ill advised trip to Vendor - or at least that is how Thirson understands it.
Twisted Ladder
# Stormhaven. Blue ? Looks onto a small well-manicured city	garden, from the visible skyline you recognise this as somewhere in	the Imperial Palace at Stormhaven
Very likely because Hentron is there 
# 
# Blue Tower, Dragonlake. Blue Wizard. Looks down onto a	ploughed field, a short distance away can be seen the sea (or	possibly a large lake). To the left is a tall tower, seemingly clad	in blue stone. This viewpoint is slightly blurred – as though	looking through smeared glass
# ??? Looks into a small antechamber off a large courtyard.	With a shock, you recognise the courtyard as being where the GARM	ritual was being enacted
Thirson points out that this is likely to be changing - even though he hated him Thirson acknowledges that T'Garth was a very good Priest and deserving of the Blue Priest title
# Trollhiem. Blue Trader. A small courtyard with a disused and	dried up fountain in its centre. You do not recognise the skyline,	although it is definitely a major city
# Roubank. Blue Witch. A small copse of trees, in the distance	you can see a wooden stockade. You recognise this as the home of the	Blue Witch
# Remains of Starport. Blue ? Is swirling with a	kaleidoscope of colours, occasional glimpses of a small lane which	has rubble lying in it. The skyline kind of reminds some of you of	StarPort
Thirson has no idea about this one 
# ??? A small hall devoid of furniture and only dimly lit. In	the hall, standing in unmoving ranks are large numbers of corpses of	various races, Orcs, Humans, Maratasen, Elves, Giants and Ariels	make up the vast majority
Thirson has no idea about this one  
# Hightower. Blue ? Inside a small cave, through the	cave entrance you can see the city of Hightower
Thirson has an inkling that one of the Smiths inside Hightower is deserving of the Blue - but the inner order of Enchanters is so secretive it is difficult to know
