If it's still available, here's a short bio...
(I was thinking Clone Wars era.)
Having spent nearly a decade on the remote worlds of the outer rim, Jedi Knight Lyron Daulot had scarcely even seen another Jedi. Missions were relayed by courier or long range transmission; life had been simple and to the point. There had been no need to concern himself with anyone or anything but himself and the task at hand. It suited him well enough. People were unreliable. That much he'd learned when his Master's sister had shown up and gradually seduced the grizzled mentor away from the Light with promises of 'making a difference' with real power. Trust was best put in one's own abilities, the Force, and the silent companionship of his former Master's lightsaber. Here, he could be at peace even amidst the constant conflict and diplomatic chaos of disorganized system governments.
Now, he was being recalled back to the galactic core to take up a mission he'd managed to duck until now: taking on a Padawan. Her failings would be seen as his own. His own weak points would be seen clearly by another for the first time in years. Nngh. Lyron was not looking forward to it. The sooner he could prove her unworthy of the mantle of Jedi Knight, the sooner he could get back to his solitude.
(It's difficult coming up with well-drawn male Jedi fan-art, but I figured a human male. Around 6'2", and roughly 32 years old. Black hair, left just a bit shaggy and wild from his time away from 'civilized' society. Orange-brown eyes. A bit of a perpetual frown on his face. A lightsaber scar along the jaw, and another across the bridge of his nose. Tends to wear clothes suited for local civilizations while on mission as often as the traditional robes.)
