Shardmind

Shardminds are a PC race new to 4e. They get bonuses to INT and WIS or CHA, they can resist psychic attacks and they're versatile. That's not the important thing, though.

The important thing is that they're made of thousands of tiny crystals, shards of an ancient gate designed to keep the Illithids and various other Great Old One-esque beasties out of the Universe. That kind of fell through, so now Ioun is busy keeping any more nastiness from getting through while the Shardminds try to rebuild the gate. Only problem is, they disagree on how to do this. Should they build a new gate, rebuild the old one, or murder each other and send their souls to the gate? Decisions, decisions.

Physically, they don't actually have genders, though some seem vaguely male or female. As for their personalities, they're a bit like Warforged - some are brooding and introspective, some are brainless dutyfags and some are wide-eyed and naive, learning about the world. PROTIP: Only ever play as this last category. Brooding is overdone and nobody wants a battle autist in the party. Wide-eyed naivete, on the other hand, leads the party to Wacky Hijinks.

Shardminds usually stay calm, but when they get emotional, they get really emotional. Like, Carrie with blood all over her emotional. So don't piss one off!
