Tenebrous Rift Kill Task

Talk to Solange in the Singularity Caul at 97.3S 94.6W to begin the task.

Solange tells you, "I've spent many of my days in the place known as Singularity Caul. It was in my travels that I made an amazing discovery, one that would surly change anyone's life. I've experienced that proximity to a dieing rift has certain effects on the psyche."
Solange tells you, "It's truely amazing. Go out and experience it for yourself. Different riffts seem to have different effects."
Solange tells you, "Kill 30 Umbral Rifts and left me know of your adventures."
Solange tells you, "The experience of hunting Umbral Rifts appears to have a heavy but short lasted effect on the psyche, on the other hand Tenebrous Rifts have a minor bug long lasting effect. If you seek to truely explor your own essence I'd suggest you kill 350 or more Tenebrous Rifts, it's truly amazing."
