Pukchep, from Martian Dreams
Like all Martians, he fled to the Dream-World when the plague killed their bodies. There, his task of composting the bodies of the dead for new life to grow was rather useless.
He explained to the Avatar in Martian Dreams that he added the remains of the Martians who die to the compost so that the life experience will pass on to new bodies through the soil. He also had worked with chemicals, but told the Avatar to ask Plashef about that.
