I'm hoping they'll have something completely independent instead, to make things that much harder on the Enemy. We'll see.

Yes.

So: Fëanorians. Opinions on when to throw things?

Yes, we were thinking of waiting until we can drop a lot at once, if he decides to retaliate in kind a lot of people will die and we will eventually have the capacity to keep him out of the air after we level Angband but we do not have it yet. Do my cousins want to risk it sooner?

That's mostly me, to be honest.

If it's quantity that's the problem, can we substitute hitting harder? We can send projectiles that would level any nonmagical fortress; the issue is whether the enchantments can let it apply to Angband.

We should be able to do that. Why do you expect you can hit a lot harder than we can?

Better equipment. We've been using gravity elementals for moving mass, and those weren't easy to get.
We can only launch things so high because this world is weird, but we can mess with the direction and strength of down, drop missiles horizontally if we need more room to accelerate or just to be safe, and the projectiles end up moving several times the speed of sound. Um, if they're aerodynamic. Accuracy's not great but Angband's a big target.

Aerodynamic is not the hard part of projectile manufacture. How many can you do that way, and how many at a time?

Varies with how heavy they are and how much force we want to use. We've been rounding off to seventy-two tons at a time; it's probably more useful to split that into barrages since they'll penetrate more than they bludgeon.

And how long between barrages?

Um, each practitioner can set up a missile in about sixty seconds if they're really on the ball. To keep it up we'd need a lot of people manning the artillery.

You have a lot of people, at this point.

We do.

I'm very sure we could ruin an Angband-shaped fortress, but the Enemy might just be immune to kinetics, so.

The Enemy is very plausibly immune to everything. Knocking down his fortress is still probably a good idea, and we cannot really fear it gives him the idea - he can't have failed to think of 'drop rocks'.

And 'magically throw things very fast' isn't that much more creative, even if he'd have to do it differently.

It'd take us weeks to enchant things to work against Angband. You could do it faster and better, but if each projectile has to be done individually we'd be talking about a lot of magic. Is it Elf-only, or is this something we can contract out to the Dwarves?

We can contract it out, but it'll be expensive.

If it's between that and spending a lot of the enchanters' time... expensive as in large purchase, or expensive as in we couldn't finance it if we started an industrial revolution?

We are starting an industrial revolution - Dwarf cities are underground, don't worry, we're handling everything with appropriate caution - and that is the only reason we might be able to afford it.

There's if and then there's if.

Would it be more or less feasible than doing it here? Because if it's less then we have enough enchantment capability to equal an industrial revolution and should probably see about buying their economy...

What have you been thinking we're doing? The main delay is travel times, it's impossible to buy something you can't communicate with very often. Anyway, asking them to do it is more feasible than doing it ourselves, but higher opportunity cost, our credit with the Dwarves substitutes for enchanter time but also substitutes for other things hard to come by.

I didn't know you were taking over their economy twice simultaneously.

Hiring enchanters was a spur of the moment suggestion, if it's not worth it's not worth it. We were expecting to have to enchant the projectiles first, and that would take weeks.

And that's too long? I was going to say 'year or two' on having a sufficient supply.

It's too long if it's longer than it has to be.

Is the year or two before or after factoring in the better launching system?

The challenge is enchanting something that will do more than superficial damage, and enchanting enough of them. 

Is it that much harder than we anticipated, or are you working from a different scale of how much damage it takes to be worth it?
