Biomuh

Biomuh is a grey material used mostly in prostheses like the robot arm. It connects living tissue to technology by seeking out nerves and joining with them. It also glues itself to bones to create a rigid connection.

Biomuh appears to activate by dipping it in water and turning on whatever device it's conjoined with. It then seeks out viable organic tissue and connects to it with produced tendrils. Sometimes, some less than precise procedures like stabbing needs to be done first to expose the nerves and bone for the joining to be successful.

It's unknown how reusable this is. The aforementioned robot arm can be used by Naigad underwater without Biomuh being activated and a friend of Bykaas's supposedly kept detaching and attaching various prosthetics to himself. It's also unknown how dangerous (if at all) this procedure is. The previously mentioned person apparently "didn't care."
