Actually, you just reminded me about him - I used the brother in Into The Dark and we had him as an addition to the plot in that, but I wasn't planning on using him here.
I made the changes because I'm bored with the character, and it was a possible transition to make. It also adds to something that I am able to do - Not to mention that this new struggle is something that can be going on in Arillious' mind throughout the RP, instead of just thinking about others. Hale seems to have some serious shiznit going on his now screwed up head, it's possible maybe Alice might be mentally fighting something later on with those visions, and even Simus can at some point get stressed with the fact that he is leading this squad of warriors who are basically the only option right now for taking down Ulfric and saving the freedom of Skyrim. This gives the RP not just a ton of physical conflict, with the same old fighting and everyone killing hundreds without dying, but it also allows us to get into some characters heads, and see what they are struggling with mentally as this is all happening.
I'm not changing my character just because I now like axes, Simus - I now have some material that now gives me the ability to delve more into the character that is Arillious. The height and weight thing shouldn't be a problem because I have never mentioned Arillious' physical appearance at all in the actual RP, and no other character has either, and with the whole half-Nord thing, Arillious has pretended to be a pure Imperial since joining Skyrim. He considers himself Imperial because his father and his later generations of fathers are all great Imperial warriors, and he wants to be like them. He doesn't want to be half Nord and that is why he has and will never mention it to anyone (except maybe later on if the whole Alice marriage thing happens, she has a right to know who he is.) But this whole meeting with all of them is starting to open up that he will need to accept both his Nord and Imperial side in order to be great. That is basically what I am planning on heading with it.
Hope this clears some stuff up - if there is any flaws tell me and I will fix them. But those were my changes and that is the new story behind it, do you still not like it Simus?
