Fairly viable embark site (by .19 standards) with iron, flux, clay, sand, river, lots of trees. Top several layers are soil, easy to get storage/farming going quickly. World genned with LazyNewbWorld so layers are compressed. First cavern is only 10 layers down but should be easy to build deeper in the solid areas. Not a volcano so wood burners will be required to start with (or see notes below), but surface level is a forest so trees are in abundant supply. Top stone layers contain hematite, cavern layer contains marble. Only other metal is native silver in the cavern level.

Now for the tasty stuff:

Slade fortress filled with undead in the lower cavern level. Top level is connected to the bottom caverns (which may be connected to the upper caverns in some way). On its bottom floor - the fabled sword in the stone.

There should be the usual amount of mine-able blue candy without opening the clown car.

It should be possible to draw from the magma tube next to the fortress without being exposed to attack, if you're careful. Maybe set your entire fortress up looking out your window at the undead!

Possible additional challenge: On my first attempt at this embark, got a double squad ambush far before it seemed like I should, something may be throwing off fortress value so prepare defenses quickly.


Objective of this challenge embark: (or at least what I saw in it )
1. Train as many dwarves as possible to the limit of their martial ability and outfit with steel or blue stuff.
2. Build some nice chairs and tables.
3. Kill everything in the slade fortress and pull the sword out.
4. TONIGHT WE DINE IN HELL!

*Disclaimer*: I don't know if it's even possible to kill the undead in the fortress in this version. But the sealed floor tile does directly lead via about 30 levels of stairs inside a column of slade, into hell.

Some part of the caverns will collapse at embark - looks like a few unsupported slade fort floor tiles falling down and crushing some undead under them. No infinitely draining magma or anything like some other HFS embarks, FPS should stay good until hell is actually breached.
