I'd like to make a proposal to have the Wayang race (from Paizo's Dragon Empires setting) available for play in LPF. While I generally like the idea of trying avoid an over-proliferation of PC races, the Wayangs really strike me as interesting, for both their fluff and their crunch, and I think they'd fit in well into our setting. I also like the idea of having a small-sized race available for play that is mechanically distinct from halflings and gnomes (whose similar stat bonuses and penalties frustrate me to no end).

As far as the fluff of Wayangs in E'n, I picture it as being something like this:

Wayangs are close relatives of gnomes, and share their fey roots. Both can trace their origins to the Hidden Path, but whereas Gnomes can be seen as much purer expressions of that path, Wayangs seem to have originated from a point at which the Hidden Path intersects with vertices of the Essential Path which express dimness and concealment, such as Darkness, Smoke, and Oil. Whether the Wayang arise from one specific intersection, or whether they are born of a multitude of them, remains uncertain. Either way, the resultant race is a muted relative of their gregarious cousins: Wayangs emphasize secretiveness and stealth, tending to be far more introverted than Gnomes, and their appearance (mostly muted grays and blacks, with occasionally deep purples, blues, or reds) reflects this.
Here's the crunch; I modified the languages slightly to reflect the absence of the the Tien tongues.

All wayangs are humanoids with the wayang subtype. They have the following racial traits.

Ability Scores: Wayangs are nimble and cagey, but their perception of the world is clouded by shadows. They have the following ability score adjustments: +2 Dexterity, +2 Intelligence, –2 Wisdom.

Size: Wayangs are Small creatures and gain a +1 size bonus to their AC, a +1 size bonus on attack rolls, a –1 penalty on their combat maneuver checks and to CMD, and a +4 size bonus on Stealth checks.

Speed: Wayangs have a base speed of 20 feet.

Senses: Darkvision 60' (wayangs can see in the dark up to 60 feet.)

Special Abilities:

Light and Dark (Su)
Once per day as an immediate action, a wayang can treat positive and negative energy effects as if the wayang were an undead creature, taking damage from positive energy and healing damage from negative energy. This ability lasts for 1 minute once activated.

Lurker (Ex)
Wayangs gain a +2 racial bonus on Perception and Stealth checks.

Shadow Magic (Ex/Sp)
Wayangs add +1 to the DC of any saving throws against spells of the shadow subschool that they cast. Wayangs with a Charisma score of 11 or higher also gain the following spell-like abilities: 1/day—ghost sound, pass without trace, and ventriloquism. The caster level for these effects is equal to the wayang’s level. The DC for these spells is equal to 10 + the spell’s level + the wayang’s Charisma modifier.

Shadow Resistance (Ex)
Wayangs get a +2 racial saving throw bonus against spells of the shadow subschool.

Languages: Wayangs begin play speaking Common and Wayang. Wayangs with high Intelligence scores can choose from the following: Abyssal, Aklo, Draconic, Goblin, and Infernal.
