Trollbot? .
That rather makes me think of a cybernetically enhanced trol of the huge grey skinnned club wielding variety, but with metallic bits in random places and maybe installed lasers.
Hmmm, I'll have to considder that one if I ever do a sequal to the horrible dungeons of dreadful doom!
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
