A Shadow Among Light (Lightwings Open)

Name: Sarkoth
Alias: The Shadow ((I will reference him by this name in the RP))
Gender:[/b Male
[b]Tribe: Rogue
Occupation: Assassin for Hire
Size: Little thing. 10 feet tall, 20 feet long, 40 foot wingspan
Appearance: Long, thin, and lanky, Sarkoth was built for stealth. His small horns form a ring around the back of his head. He can move the ring ever so slightly so he can fit into spaces more easily if need be. He has no spines down his back, though his tail ends in a poisonous barb. His eyes are bright, toxic green, and set low on his face.
Personality: Cold and cunning, Sarkoth doesn't talk much. He's not a coward but-like most assassins-he'd rather run and try again later than stay and push his luck. He turns tail the second he's discovered (which is almost never) to hide and wait until the next opportunity arises.
Powers:
-His scales, while not actually changing color, reflect light differently depending on the angle he sits in the sunlight. His natural color is black, but if he orients himself the right way in the light, he can appear white simply because of the way his scales are angled to reflect the light. Because of this, he is fully capable of hiding in plain sight, though he much prefers the cover of darkness, where's it's easier to hide and not be seen.
-His wings are massive and the scales on them allow for almost completely silent flight. Only in absolute silence will you hear his wing beats.
-His feet are padded similar to a feline's for the same reason, no noise.
-He can fit into spaces you wouldn't expect even for his small size due to his extremely flexible joints, and even his bones themselves will bend slightly before breaking
-His tail ends in a poisonous barb, the venom from which is fatal even in small doses. (The poison basically paralyzes the target over the course of a few hours (roughly 4-6 depending on the size of the dragon), radiating outward from the injection point. The dragon is fully paralyzed before the poison actually does anything life threatening like freezing important organs and such.)
Weaknesses:
-His size. Tiny little bugger, couldn't stand up to most dragons to his size. Heck, most dragons could probably step on him.
-No muscle strength of any sort. He relies purely on his poison to fight
-The bending joints/bones is extremely painful and leaves him vulnerable for a good while after he does it to recover
-His scales reflect light differently from the different angles he's seen at, so at one angle he's invisible, while from another he might be extremely obvious
-The poison must be injected. It cannot be ingested or absorbed. Meaning he has to find a weak spot in the dragon's scales to administer it. This could be a missing scale, a large enough gap between scales, a cut of some sort, anything where he could get under them. If it's not injected, it's harmless
-The poison takes so long to work it's easy enough to find and make the antidote before the dragon is even half-paralyzed. If you know what it is

The antidote: A mixture of common berries and flowers. the combination of the different plants somehow nulls the effects. any part of the flower will do, but it must be the berries off the berry bush, berry leaves won't work (daisy, blueberries, poppy, strawberries, and sunflowers) crushed and mixed up to make a juice. A dragon must drink it, and the effects are reversed at roughly the same speed as they were initiated. It must be done before the poison begins to affect internal organs though.
