I do think Itar's point has some validity, and I will flatly state that Tir Esias is by no means a traditional force user.
He (as of yet) does not carry a lightsaber. In fact, most of the time he has a bodyguard he walks around to protect him. He could use his cane (and the technique that Vodo taught him) to ward off attacks.
I would like to reserve the right to someday build a saber, if I ever felt that Tir's character called for it. Of course, on the basis of the common sense rule, it would require serious attention to obtain any level of proficency.
Of course, Tir's obvious handicap would limit his potential and reduce how effective he could be as a swordsman. But thats another matter.
Tir uses the force everyday of his life, and has since his right after his birth. He uses the force to compensate for his lack of vision, and its use comes as second nature to him.
Having (before working with Vodo) never really trained his talent, he was often using great amounts of the force to do things that Jedi would do with ease. He still has something akin to the "touch of a blacksmith"- he has a large raw potential and a great amount of power to draw on, but his ability to concentrate and focus that power is limited.
He has imporved since working with Vodo, but he is no master.
The greatest emphasis of his manipulation of the Force (outside of mundane everyday usages, which I often reflect in passing) has been on battle coordination- not Jedi Battle Meditation Mind you- of the Union's necrotroopers.
[thread=7867]Necrotrooper R&D/info thread[/thread]
[Brief synopsis- Necrotroopers are soldiers employed by the Union itself (as opposed to its sub-factions) that are either clones or captured civillans/slaves that have been rigged up with implants that basically eliminate their free-will. As such, I have made it so that Tir can very easily touch their minds as they (well at least most of them) are effectively drones]
Tir first controls Necros ICly here:
[thread=6663] Infiltratating[/thread]
And goes on to do this on a larger scale (and after a signifant passage of time) here:
[thread=7763]A Score to Settle, A Price to Pay [/thread]
Also, I am sure he would (and has, in some small references) interact with necrotroopers on a smaller scale. He may even have done so in the original training thread with Vodo.
I hope those help. And I'd be happy to answer any other questions.
