A pained shriek of agony echoed through the tomb, Yerbol's lightsaber crackling to life as he ran to the end of the hall, grimacing as he went right, hoping that the traces of the scream could lead him to the source. Once he reached another intersection, visceral grunts came barreling from his left, the young Jedi leaping into the air to avoid a charging Tuk'ata and a rather angry Shyrack following in suit. He had seen both creatures in holovids before, but to see them in person...it drove home how disgusting they actually were. With his feet now firmly planted on the ground after the jump, he threw his lightsaber at the Shyrack, the winged creature dodging the initial throw, but the return arc sliced it in half, gore spattering onto the ground as Yerbol's lightsber returned to his hand in time for him to dodge the other attacking creature, rolling to the left before popping back up and thrusting his hand forward to push the creature back. 

Nothing happened. 

"So you ARE force resistant." The Tuk'ata snorted, then charged again, Yerbol waiting until the very last moment before pirouetting left and slicing horizontally through the skull of the creature, the top half of the monster sliding onto the floor before the bottom collapsed. While the lightsaber was an instant cauterization tool, it didn't prevent the stench of death from wafting into one's nostrils. As his nose crinkled, Yerbol decided he would walk down the same hallway that the creatures had come from. It was a hunch, but he felt that the source of the scream might have come in part to the creatures of the tomb. His large frame darted down the hallway, then right, which opened into a large room with an obsidian colored tomb in the center, five pillars surrounding the grave in a hexagonal manner. Adjacent to the tomb was a woman with a lightsaber and on the ground next to her was...
"Lysa..." Even in the dim lighting, he could identify the curly, raven colored locks, the dark green tunic she always wore...

"You...what did you do to her?!" He could smell the faint aroma of burnt flesh, feel the heavy sensation of loss...

She had killed her...or had she stumbled across the body? 

"No...no..." His jaw clenched, the young Jedi raising his lightsaber.
"This might be a mistake, but I'll give you a few seconds to explain why you're standing over the corpse of my sister before I kill you." Anger seethed within his body, seizing his limbs, blinding his mind to the Jedi code he had tried so strictly to follow.
