In a very optimistic future...
You have checked, triple-checked, and triple-checked again the Waystone connections between Karaz-a-Karak, Karak Vlag, and Karag Dum. So, too, has the stability of their defenses and defenders been deemed adequate... at least, as secure as any holds on the doorstep to Chaos can be. You know all too well how suddenly such might change. Still, for now the Throne of Power has a surplus of magic; just enough to reactivate one of the long-lost Great Works of the Ancestors. But which one?
[X] The Eyes of Grimnir: Reactivates the thousands of hidden monitor runes throughout Silver Pass. Allows the retaking of Silver Pass and the mountains east of Karaz-a-Karak, and greatly reinforces the defences of those mountains if they are under Dawi control. Also potentially allows the retaking of Karag Agilwutraz, gaining control of the eastern side of the mountain range and regaining access to one of the richest silver mines in the world.
[] The Third Axe of Grimnir: An axe carved out of a mountain and under the control of Karak Kadrin. Allows the annihilation of all enemies of the Dawi along Peak Pass. This would greatly secure Karak Kadrin, allowing their trade to flourish and some of their local forces to be re-allocated. While it holds, this would also severely blunt if not outright end any invasion from the Dark Lands.
[] The Gas-Forge of Morgrim: Enables the production of Hydrium, a gas that is lighter than hydrogen yet also non-flammable. In turn, this would allow for the recreation of the ancient airships that once dominated the skies. Each airship would not be cheap, but their designs are as venerable as any engineering project.
[] The Great Pumps of Morgrim: You won't activate this now. Instead, a massive flood-path will have to be carved. Once finished, the Varn Drazh lake can be drained, allowing access to the fallen star's massive Gromril deposits at the lake's bed. This will also give you the ability to redirect the flood waters along their original path, allowing the complete destruction of Stirland at a moment's notice. But what the humans don't know can't hurt them.
[] The Sally Port of Gazul: So many Dwarfen souls are lost each year far from the protection of Gazul's priests. It would be a boon to save them, even for a short time. Yet the spirits from the Sally Port are said to only care for the dead. What help would they give the living, if they would do so at all?
[] The Tectonic Shackle of Thungni: Calm Thunder Mountain's rage, enabling it to in theory be retaken from the Grobi and other monsters that inhabit it. The secrets of the Rune of Sorcery and the construction of the Anvils of Doom could possibly be reclaimed, yet at what cost?
[] Altdorf and The Colleges of Magic: While the twin debts owed to Loremaster Weber and the late Sir Wulfhart the Valliant have been repaid, it could be said there is a larger obligation to be seen to. It will be a long time before the Empire of Man fully harnesses its own Waystone network. In the interim, you could lease them the use of your excess power for a short period of 20 years, giving then a head start on creating their own shoddy mega-projects. You have no idea what they'd offer to repay you with, but the price you will charge will be very, very,
very expensive.
A/N: Just a quick little what-if from Thorgrim!Quest, using the bits mentioned
in this update and a few notes from the wiki. Hydrium is a reference to the Airborne novels by Kenneth Oppel. (Which I haven't read in, uh, a decade? Eh.)
Edit: This has been slightly revised. It's still an AU, but I've changed a couple small things to reflect new information.
