OOC:
Evelynn has no glowrod, not really needing it, but I assume the others have some sort of illumination.
As she leads the way into the large stadium-like cavern, Evelynn recoils as the massive surge of fear, rage, and death wash over her. Even without opening her senses, she can feel the dark side presence in the room. As Zepharo skirts the edge, and Ian unlimbers the rifles he carries, Evelynn takes a step forward, towards the obelisk she can feel in the center of the room. As she does, she attempts to reach down into herself, to call forth the light side of the Force and tries to project it outward, a counter to the darkness she feels clinging to the chamber.
OOC:
I was thinking to maybe make a Discipline check, with or without a Force die maybe, to try and draw on the lightside. Help to bring balance to what she thinks could be a Force Nexus, if she knows what the is. She is intentionally not drawing a weapon as she moves, also.
