Science

Science is broadly divided in to two discplines - alchemy and biology. Physical sciences and engineering are comparatively underdeveloped. Dr Frankenstein would be at home here, but steampunk engineers not so much. The science aesthetic in Obscura can be described as "Leonardo da Vinci meets Dr Frankenstein", or "better living through absurd biochemistry".

Alchemy

Alchemy is the quite involved science of fusing elementally active ingredients together to get interesting properties.

Biology

The main focus of biology is study of the human body. Surgery and medicine is an obvious practical application, and health care in the world of Obscura is very good as a result.

More extreme applications of the study of the human body are Grafting and Reanimation.

Grafting

It's possible for advanced surgeons to graft elemental material in to the human body, deliberately causing the person to become elementally touched. This will likely take quite a bit of elemental material for all but the simplest grafts, and so far such material has only been found in small amounts at random, limiting the progress made in this field so far.

Those skilled in Advanced Grafting may be able to come up with personal, experimental grafts based on elemental material or even surgical implantation of alchemical substances. These could be much more powerful, but will likely require regular infusions of material to continue to function, or have other drawbacks.

Reanimation

Biologists have managed to reanimate dead human bodies, in a limited fashion. Attempts to reanimate animal corpses have always failed. There are two proven applications of this discipline.

The first is the ability to animate a body to speak again as if it were alive. They retain their personality, so you can generally expect them to be exactly as cooperative, or uncooperative, as they were in life.

The second is the ability to bolster the body of someone who has received terminal injuries to act normally again. This is not real healing however, so while this can allow them to make the best of the end of their life, it cannot extend it.
