Elminster's Ecologies Appendix II: The High Moor, The Serpent Hills (AD&D, Forgotten Realms)

An excerpt from A Treatise on the Life of the High Moor by the druid Bara:
The
environment includes such things as terrain, flora, fauna, weather, and
natural and arcane forces. All these elements - each aspect of the
environment and each organism - form a tapestry known as the ecology.
And like a tapestry of cloth, this one can suffer severe damage if a
single thread is removed, no matter how ugly the thread.
This appendix includes two booklets penned by friends of Elminster of Shadowdale. Collected here are:

• a 32-page booklet containing the words of the inimitable Bara,
  feisty druid of the High Moor, describing the ecology of that region;
• a 32-page booklet by the Lark of Suzail that gives her descriptions of the slithering inhabitants of the Serpent Hills; and
• a brief booklet of tables to aid the Dungeon Master in determining
  random encounters for adventurers whose travels take them through these
  areas.

Those planning to explore these regions would be well advised to
read the works herein to prepare themselves for the reptilian dangers
of the Serpent Hills and the hazards of the High Moor - from the beasts
to its protective druid herself!
