For all of you, the presence of Lemugem is frightening. Even those immune to fear comprehend the power of the individual. The fact that you are all spellcasters makes it more palpable. Having just been the in presence (sort of) of Smofarf, and recently the Collector, it is a different feeling than those experiences. There is almost an electricity that surrounds Lemugem, causing the hairs on your neck to stand with magical force. However, unlike the presence of Smofarf pulling at your soul, Lemugem has no such effect.
On the other hand, Ralf is a true nightmare. He presence is unsettling. Your mind has trouble focusing when he is near. A sense of uncontrolled spiraling into chaos tugs at your mind. Any detentions used on him reveal a different result every round. Whatever he is using to move around unnoticed is as powerful as a Superior Invisibility, but somehow different. As if in any given round he is a combination of invisible, displaced, ethereal, astral, incorporeal, etc. It changes every round, as if he is just 'not there'.
