Proposed Canon
First Appearance: TBFGK 21
Schlemiel Elves are an Elf brand.
Schlemiel elves are unimpressive combatants, small, weak, and poorly skilled. When faced with any sort of serious opposition, they tend to die in droves, a fact not lost on the Schlemiel elves. It is possible that their combat deficiencies are balanced by a low pop/upkeep cost, or bonuses to negotiation, such as convincing a side to pay an exorbitant fee to forge an alliance, or perhaps they can pop mathamancers.
 Real World References
Schlemiel is a Yiddish term for a 'habitual bungler,' and is commonly used in Jewish humor as a term for a ne'er-do-well character who serves as the butt of misfortune.
