From HGWiki

Grey Renders populate this area, True Seeing is advisable (potions available in (Rip's Wretched Brewery) as they cast a conceal effect making them difficult to see or hit effectively. They also cast several annoying spells. Some of the ability draining spells they cast may empty your spell book requiring a complete redo once you've finished here if you are a not a spontaneous caster (sorcerer or bard). If you are a caster that relies on a chat command to populate your spell book (e.g. Assassin, Blackguard, etc.) you will need to commit all of your spells again. Not advisable to stand in the sand here due to the static charge it generates unless you have good electrical immunity/resistance.
