Yeah I picture this Thrall and Horus as being characters whos destinies are intertwined. That he isnt just his perfect bodyguard, but that in the future during Horus's conquest of the world, he would be his chosen general, leader of his armies, his second in command. That despite the fact that he is Horus's thrall, his psychic puppet, that he is the only being in existence that Horus actually has any semblance of respect for, because although his ability can call any variety of beings to his cause, that does not mean that they are all usefull, wise, capable, knowledgeable or skilled. That despite the fact that it was his thrallherd call that brought the thrall to him, that they already had similar goals, that even before being called to Horus he longed to bring true order to the world, an order that would bring the world under its wing for the betterment of all, that some would welcome such a change but that others, others would need to be shown the way through force, or purged in order for a new world order to come into being. That he always longed for a cause, for someone to show him the way and give him real purpose. That even if it wasnt the Thrallherd Call that brought him to Horus, he would willingly have served his cause. That even without the psychic bond, he would have been a true believer.
As far as alignment goes im thinking neutral evil just like Horus. Even though he believes that in the end the True Order, will be for the betterment of all in existence, it does not change the fact that his, "The ends justify the means", attitude is still evil, and that just like Horus, he may not be chaotic because there is an order to his life, but he doesn't believe in working within the constraints of the laws of imperfect Mortal beings and will do whatever is necessary to further his lords goals, which are also his own.
So yeah, the idea that is by far the most appealing to me is Psychic Warrior 5/War Mind 10/Psychic Warrior 5.
At level 1 for his bonus feat he will take Weapon focus and for his power he will take Call Weaponry as his power, as is requirement for the Soulbound Weapon ACF. His second level bonus feat will be substituted out for the Soulbound weapons ACF.
As far as Race is concerned im going to go with Half-Giant for sure. Im thinking that maybe his family were merchants from the hill giants home city in the desert and thats what brought them to Tarbean (the city our campaign is set in).
So I still need to figure out the rest of his feats, what weapon he will take, im thinking something double handed, im going to check out that flail in a minute here. Since he is a Half-Giant he can use weapons that are one size class large then him so that will be good.
As far as skill go im going to try to find that entry that lets Psychic warriors switch out ride for tumble. For the war mind reqs ill have to dump some points into Knowledge psionics and Knowledge history but other then that its gonna be concentration, tumble, and autohypnosis, then maybe spread the rest of the points between jump, swim, climb etc.
So what do you guys think?
