Namus

Namus are a race of aliens that are the reincarnation of dead humans, they have no memory of their time as a human while they live their first life on Namulia. But once they die again they regain all their memories. they cannot die a third time. their immunities from both deaths stack (say one has a fire immunity and then they die of cold, then when they're a 2 death (on their last life) they have both immunities).

Appearance
Once a human gains any memories the generation process starts for what they would look like as a Namu. Every moment of their life causes a subtle change to the Namu's appearance. For example, say one day if you died you would spawn as a green Namu, but if you died a few days later instead you would be a lighter green Namu. (Please note this Namu does not exist until the person dies, the data is just kept in code.)
