Trying to get feedback on the nations of a world

[brian 333]

I would think the Stoneborn would be the least interesting of the races, but they seem the least developed as well: this may be a cause and effect relationship.

I propose the following:

That because of their origin in a lake of Arcanium, they are immune to weak magic and resistant to strong magic. This only includes magic against which they would be entitled Fort saves, and not the effects of spells which create harmful by-products.
Thus, an Acid Arrow or Fireball, in creating acid or fire, would still be harmful, but a Magic Missile would be too low level to bother an automaton, and the automaton would be very resistant to Polymorph Other.

That in order to reproduce or heal, a Stoneborn requires Arcanium. This makes it a prescious commodity to the automata, who view the use of it by other races as wasteful. The primary goal of the automata would be to secure the liquid magic for their own use, co-operating with others only to the extent that it allows them to access and eventually secure the material for their own race.

That unknown to all save a handfull of dwarven loremasters, the Stoneborn created by the dwarves still retain the command codes by which the dwarves controlled them. Only dwarves, gnomes, and halflings, (and their mixed-blood offspring,) can use these codes which, at the time of their creation, was a complex language used to instruct the mindless machines in their work. Only a few phrases survive and only a very few dwarves even know they exist.
Second generation and later Stoneborn have fewer or none of these codes and are thus less likely to be controllable.

Given this, I would play Alchemist 333, an automaton whose mission is to access the new deposit of Arcanium and map its locale for the use of its race in eventually securing the deposit for the exclusive use of automata.

In addition to this mission, Al has a personal quest to secure enough Arcanium to enable it and its partner Lapidary 1242 to procreate. Currently Lapi resides in their home town waiting for Al's return.

As are all Stoneborn, Al is physically robust, but it relies on its intellect and its growing menu of magical potion recipes while adventuring.
