You turn what was once a warboss' lair and has been your bedroom for the past few years into a lovely foyer, adding to the existing atmosphere provided by 360-degree windows with a Rune-powered fountain and a number of scattered seats and tables to create a relaxing, airy atmosphere, only slightly detracted from by the foreboding steel pillar radiating the opposite of light in the center of the room.
You know, this reminds me of a particularly nice public library near my old secondary school. Its been ten years since I've last gone there. Its a nice place to read and generally invites whoever thinks they might be welcome to socialize here.
The hellfire pillar aside.
They didn't have that.
You also expand the balcony in every direction, adding some slanted chairs made of sturdy Dwarven carpentry to allow for reading or conversation in the sunlight - the penthouse is high up enough that there's a chill to the air not present at ground level, but direct sunlight is more than sufficient to banish it and being able to choose your angle means one could follow it throughout the entire day if they were so inclined. As a side-benefit, the extended balcony would also allow for a gyrocopter to drop off a passenger if, for instance, the Grey Tower needed to be activated on short notice.
If this wasn't the top of a mountain it'd be packed full enough to need a lottery rotation.
As it is, whoever comes up to read must not have skipped leg day.
A layer down, a sitting room takes shape into a permanent meeting place for the local wizards of Karak Eight Peaks and a miscellaneous meeting room for any other purpose, and adjacent to it the recipient of a great deal of monetary investment, your large and growing library.
Like the Journeymanlings.
Going to have serious thigh power after a few years. Just think of Panoramia taking the hike.
Either that or they'd drag a bedroll up and sleep in here
After some thought you've split the room into three sections, only two of which would be apparent to most visitors. First is the Public section, filled with information on the sciences, arts, civilizations and Gods of the Old World, that anyone who's been allowed into your Penthouse could be reasonably assumed to be cleared to peruse. Second is the Collegiate section, where any of the wizards of Eight Peaks could find topics similar to the ones in that of their own Colleges, ranging from magical theory to spellbooks to recent papers to information on the many enemies of mankind. And finally, your hidden Restricted section, filled with books on the topics of Dark Magic - entirely for the purposes of combating it, of course.
So Public section would be an asset to whichever of the Undumgi is brave enough to come up for reference materials. Probably not TOO likely unless we've suggested they take advantage of the library.
Then we have the Journeymanlings section, where they would be taking full advantage.
And the restricted section is expressedly for Mathilde to grant task specific access, though I think Johann is likewise allowed, they're our books and Mathilde would certainly want to know what they are looking into to begin with.
And below that, the more private portion of your growing home. Firstly a bedroom, which you plan to upgrade with silk sheets once the weaver situation is sorted out, and new silk sheets, rather than ones stolen from a Naggarothi like you'd heard now adorned Johann's bed.
I really hope he had those thoroughly washed.
It also featured a bed for Wolf, a wardrobe for your spare robes, and a bookshelf for your recreational reading, which you'd absent-mindedly placed in the Sciences and Arts section of your library before realizing your mistake and quickly relocating them. A bathroom, which used a combination of petty enchantment you performed yourself and small pieces of runecraft performed by apprentices borrowed from the project above during downtime. The combined effect allowed for water of just about any temperature on demand, which in turn allowed for an Kislev-style sauna, a Wurtbad-style hot bath, and water sprays quickly put to use when Wolf got into the mud of newly-irrigated fields.
Mmm, decadent...AND useful. Mathilde should be aware of the Skaven keen sense of smell, so a hot bath before should help deny information. And a hot bath after should keep Eshin from realizing what kind of captive we have.
More later, its rather late and I need to sleep
