Different hypnalises deal with such interlopers in their own ways. Some sinister or young and hotheaded hypnalises hunt such trespassers for sport, tormenting them for a while before killing them or expelling them to the Material Plane. Other older or inquisitive hypnalises are more curious about such strangers and pragmatic in their dealings with them, approaching interlopers in attempts to find out their method for traveling to the Ethereal Plane and whether or not they can return. If they can, these hypnalises might request that these interlopers leave, backing such requests with threats if the interlopers seem uncooperative. If the interlopers don't have a method to return to their home, some rare good-natured hypnalises may help them find a way to leave the Ethereal Plane without using its poison. Even when this is the case, hypnalises are wary creatures, and are always on guard against treachery.
