The troll shambled closer. He was perhaps eight feet tall,
perhaps more. His forward stoop, with arms dangling past
thick claw-footed legs to the ground, made it hard to tell.
The hairless green skin moved upon his body. His head was a
gash of a mouth, a yard-long nose, and two eyes which drank
the feeble torchlight and never gave back a gleam.
[...]
Like a huge green spider, the troll's severed hand ran on its
fingers. Across the mounded floor, up onto a log with one
taloned forefinger to hook it over the bark, down again it
scrambled, until it found the cut wrist. And there it grew
fast. The troll's smashed head seethed and knit together.
He clambered back on his feet and grinned at them. The
waning faggot cast red light over his fangs.
