Riven Mind
Once you were drawn deeply into a hivemind, such that you lost your sense of self entirely. When the hivemind ended, you had to rebuild your identity, and even now decades later you sometimes feel like nothing mattered as much as when you were bonded so fully with the minds of others. You have a knack for understanding people’s thoughts, but likely have drifted through life, perpetually disappointed by the shallowness of all your relationships, accomplishing little of note. Consider what has shaken you out of this long fog to begin adventuring. What do the people who were part of the same hivemind think about you, and do you keep in touch?
Common clothes, a winter blanket.
Some lingering telepathic potential causes the emotions of those around you to bleed into your own, and it took a long time to learn how to keep them at bay (or perhaps you are still afflicted in the presence of crowds). You find it easy to blend into crowds and not appear out of place, regardless of your attire, as long as you don’t draw attention to yourself. You can extend this same inconspicuous sense of conformity to creatures traveling with you.
Sometimes you can sense who in a large gathering feels out of place. You can focus and try to deliberately receive these epiphanies, but there is no guarantee you’ll learn anything.
When you encounter creatures which were once part of your hive mind, you gain a bit of your old sense of purpose. Once you have met several such beings, you may gain a special form of telepathy which works at any distance, but only with your former hive mates.
