From Ardrana

Sprites are shy and reclusive faerie people who dwell in meadows and wooded glens. They have distinctly Elven features and small, semi-transparent wings. Humans often mistake sprites for butterflies at a distance, and it is guessed that the majority of forest creatures also think of the fair sprites in this way.

Sprites are very flighty, and find even Elves much too serious about most woodland affairs. Only druids deal with sprites regularly. Some druids even receive a little of their training in the company of a few sprites. Most sprites love druids, for their neutral alignment and love for nature make them see the forest in much the same way. On rare occasions, sprites associate with rangers as well.

Sprites are loosely tribal, electing the best warrior among the group (male or female) as the group spokesperson. This leader is recognized as the one who makes major decisions and bargains with druids and Elves. Sprites rarely wait for their leader's decision, often attacking an evil creature before the leader can issue any command.

Note: Sprites originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
