[X] This is Dawongr Weber's money. The funds will largely go projects within the Karaz Ankor - your tower for one, but also investing in the Undumgi or Ulrikadrin, or purchasing goods made by Dwarven artisans or sold in the markets of Barak Varr.
This is an excellent time to invest to invest here, should be very profitable and accelerate KEPs development, making it much safer.
[ ] Karag Nar penthouse
The first possibility that leaps to mind is the uppermost dwelling of Karag Nar, with a beautiful 360-degree view and a commanding position. The Black Orc Warboss' reasons for taking it for his own are obvious, and though it will take some time and effort to clear out the possessions that hadn't been safely stowed in the King's Armoury, it is bursting with potential and would allow you to keep a careful eye on the Undumgi and Death Pass.
It's a very nice place, but perhaps... too nice. Would be much more appropriate to the Karaks Mayor or something I think, and it would not be even remotely hidden. Also, any spectacular magical failures of ours would be rather visible, which would be... bad. Let's go somewhere more out of the way instead.
[ ] Karag Lhune secondary peak
The second possibility is the secondary peak of Karag Lhune that the greenskins positioned their Doom Diver battery atop. The landing pad atop it was made redundant thousands of years ago when a full hangar was built atop Karag Lhune, and it's just as redundant for modern gyrocopters as it was to ancient airships so it would be yours for the taking. The storerooms below offer plenty of room for expansion and you'd be conveniently close to the heart of the resurgent Karak.
Karak Lhune is the dwarf one, Nar is the one given to trade and humans. Lets not set up a mage tower on top of a dwarf filled Karak please? Dwarfs wouldn't like that thought they might allow it, and they are bros.
[ ] Citadel Tower
Third, the Citadel is being repaired of the damage that Kragg and cannon dealt to it, as well as three thousand years of neglect, and though the two towers were once a key part of its defensibility, with the only enemy approach being within the caldera that height advantage should no longer be needed. It makes for a much more traditional Wizard's Tower than one in a mountain peak, and though it's currently part of the defensive line against the untaken parts of the Karak, that also means that there'll always be plenty of protectors on hand, and perhaps you'd like to be able to help repulse any attackers.
We are not a battle wizard to make full use of this, and performing magical experiments in a so vital defensive position, that could result in suddenly: daemons, or exploding into district devouring shadows does not seems wise to me.
[ ] Karag Nar temple
Your previous 'tower' was nothing of the sort, and perhaps you wish to continue that trend. If so, the site of you and Ranald triumphing over Gork and Mork would certainly be equally auspicious. It's a convenient distance from the population centers of the Karag and has a nearby side-entrance you could properly conceal and keep for your own use. (note: if you don't choose this as a tower, you can still use it in the future for a shrine or some other purpose. Nobody but you, Belegar, and Kragg know its significance, and everyone else just sees it as a former greenskin temple an inconvenient distance from the rest of the Karag.)
Definitely an option, though the place would be far more appropriate as a shrine to Ranald I believe.
[ ] The Grand Abyss
If you value secrecy over all else, you could go just as far down as you can up. Deep below Karag Lhune lies the Lhune Deeps, and below that is the Grand Abyss. The Dwarves never were able to plumb the extent of its depths, and that is somewhat concerning, but it would certainly be impressive to have a tower built atop a bottomless pit.
Well. Might have some synergy with Ulgu maybe? Not sure. If we go with interior intrigue it might synergize too. Otherwise, seems like a somewhat foolish showing off. Definitely safely out of the way though, if something goes wrong. A decent option I think.
[ ] Und-Uzgar
Soon to be an outpost for the Undumgi, Und-Uzgar was the site of your shadow becoming outputtingly independent. Built into the side of Karag Lhune, it boasts a commanding view of Death Pass and the passage to the rest of the Karag will be excavated any day now.
A decent option, though it having such a good view means that it should be a pretty visible spot in case of oops. I like that it is the side of a place where we got an Arcane Mark, should be a constant reminder to remain careful and humble.
[ ] Eastern Valley tower
Though it's soon to be filled with Halfling fields and cottages, they'd be happy for you to become their neighbour, and if you want to start from scratch you certainly have enough wealth and favours accumulated to build a tower of your own.
Meh. Halflings are good people, but we would be starting from scratch for no reason.
[ ] The Silver Tower
Legends of the Silver Tower have been told and retold a thousand times over - the place where plucky adventurers caused the downfall of the Gaunt Summoner. You're not entirely sure if this is the same Silver Tower, but you could make a claim on it even though it is built upon the as-yet unreclaimed Karagril.
Hubris. Lets not.
[X] There's a growing concentration of royalty here. Get to know King Kazador, and this 'Sky-Thane' Prince Gotri.
This suggests a future assisting Karak Eight Peaks with foreign relations, as a Spymaster focused on threats outside the Karak.
I don't like what it suggests, but I want to read more about those people...
[X] Scout the rest of the Eight Peaks, to find out what other horrors are waiting out there.
This suggests a future assisting Karak Eight Peaks with its reconquest, as a Spymaster focused on threats within the Karak.
I maintain that we are extremely well suited for this, it needs to be done and external intrigue would be a waste of our talents. It's also fun.
[X] Convince Esbern and Seija to stay long enough to deal with the spiders in the Chiselwards.
This suggests a future assisting Karak Eight Peaks with its reconquest, as a Spymaster focused on threats within the Karak.
Spiders need dealing with, and Beast mages are very well suited for that indeed.
[X] Claim the site where Ranald mugged Mork and build a shrine to Ranald there.
This suggests a future assisting Karak Eight Peaks, as leader of the Undumgi and point of contact for the Ulricans.
Not a big fan of being a mayor, but that place is just perfect for a shrine to Ranald.
[] King Belegar is allowing you to use the King's Armoury. Recover your extant study materials from Stirland and tuck them away safely in there.
This suggests a future catching up on your pre-existing study topics.
That-which-shall-not-be-spoken-of would be utterly safe in there. That said, spending an action on that, when our other study materials dont need such security, does not seem wise. Not to mention if we choose to study it, while we are doing it it would be outside of the vault and discoverable to people snooping around... we could also probably ask Belebro to keep just the box in there separately for less of a cost. Overall, not sure, but probably not.
[] Convince Esbern and Seija to stay long enough to hatch the supposedly Lustrian eggs and study and possibly train whatever hatches.
This suggests a future catching up on your pre-existing study topics.
Not quite sure here either. What would we even do with those beasts? And eggs are far easier to transport that baby monsters. Getting the eggs identified and selling them to the Imperial Zoo or the beast mages seems like a much better idea.
[X] All this time away has made you miss your friends. Visit Anton and Wilhelmina.
This suggests a future in Stirland, whether Roswita likes it or not.
I am not a fan of returning there full time, but visiting our friends, taking a look at our investments and assets, and maybe help out from time to time I fully support.
[ ] You're going to have a rough time explaining your windfall to the Bursars. Better to get that over with.
This suggests a future performing an assignment the Grey Order thinks is suited to you.
I like the suggests part, but meh on the option itself. Not urgent. I would fully support donating most of the gold to schools, healers, and orphanages anyway.
Edit: Convinced by Alectais post above.
[X] Write a series of papers on the magical phenomena you witnessed. Or better yet, get your Journeymanlings to do the actual writing.
This suggests a future of investigation and study at Karak Eight Peaks, and perhaps helping Johann poke at Skaven technology.
The conflict with the High King is very interesting. I think that I'm glad that it happened. It shows that Belebro is rather firmly on the side of growth and prosperity for his people rather than self destructive vengeance. This is good for the survival of dwarf-kind, and all that are sane.
I like to think that the High King approves, but can't really say that out loud because politics.
A bit sad about not seeing what the grudges we have helped resolve would be worth though. As for the lack of a reward for them or the inability to spend favour Karaz-A-Karak, meh. We can do without. Worth it.
