World topography created with perfect world, with standard generation of history and minerals (scarcity value of 600) . Mostly some light graphical and QOL mods, but two that change gameplay,

(2Handed Weapons)
and
(Vanilla Weapon Overhaul)

Which makes some small adjustments to weapon size's so that dwarves can wield (and craft a few) large weapons, and adjusting the contact area of some attacks (nerfs the whip and scourge, but other changes are more-so balancing/niche defining changes)

The world contains a special dwarven civ in the south, which if my understanding (and the wiki's contents) is correct, should have necromancers with extra abilities, as they worship a deity of death, and night. directly to the west of this civ, is a large mountain range, (after several embarks to verify) comprised of an obsidian and gold igneous extrusive layer, and while not shown pre-embark, there is some hematite clusters at depth and small aluminum clusters a few layers below the obsidian surface, it should be noted that this mountain range is isolated your only companions will be your parent civ, the kobolds, goblins, forgotten and mega-beasts.
