...  you to contine to descend
a staircase through the catacombs and under-world until the caverns lead to undergrowth and overgrown weeds, wet damp and mutant plants! Vast foliage and forest! You are obviously on the edge of a deep forest... running water & rain, perilous crevasses- trick the mind into its senses - ... to follow the path by the waterfall seems the best option, going through to the forest seems to have eluded the THalos Sentry...
you have certaintly left the gloomcity now..... out past
the sewer drains ....
all that is here are parts of the undercity and the 
strange primeval forest beneath....
your feet become wet, as reeds lash out, curled up among
sodden rocky outcrops,

you can hear the sound of           rushing water nearby;




the cries of strange creatures howl from an unseen valley
