Having placated Firozet and warmed his chill, Gitaena, Faethor, and Eladithas join Beezhul in chatting him up about his design.
Gitaena has picked up a thing or two about arcana so she tries to link what she knows to the idea Firozet outlined. "Have you considered combining the capabilities of water and fire elementals to create steam? If water is turned to steam in an enclosed chamber with something like a piston at one end, then the expanding steam would push the piston, which could then be linked by gears and shafts to turn wheels."
Arcana: 1d20 + 4 ⇒ (14) + 4 = 18
Firozet smiles at her and taps a cylindrical tank laying length-wise on the front car of his train model.
That is precisely what's happening here. Great minds think alike! You seem to have some experience with the elements! What have you invented with those primal energies?
Faethor takes a peek at the elementals.
”Air elementals can be a flighty bunch. It takes a firm hand, but not too firm or you'll just push them out of your grasp.”
Nature: 1d20 + 5 ⇒ (18) + 5 = 23
He bobs his head in a sort rhythmic consideration of the point, replying They can, but we can also harness the element through a planar gate that utilizes the raw energy and not elemental entities. No Living Whirlwinds were harmed in the making of this train model!
He smiles enthusiastically, satisfied with his response.
Elidathas converses with the Godless Arcanist.
"I am trying to understand the fundamentals of your design, but find myself at a loss. Can you explain them?"
Nature (T): 1d20 + 8 ⇒ (1) + 8 = 9
Oh dear, oh dear, oh dear. I can't break down the elements any more fundamentally. They are, in fact, elemental.
Firozet explains that through gentle applications of planar binding, minor elementals of air and fire can be used to create superheated air. This in turn is directed out through a large vent in the back of the train, causing a horizontal push that will propel the train.
