Totem and Saimhe:
I will not be subtle here. What does Howard seem to share in common with Charr?
Writing style? No...
Personality? Definitely not.
History? From what Howard has said, not even close.
All Howard? seems to have in common with Charr is your unreasonable hatred. I think you're jumping to conclusions here.
Howard:
Ramone: Dr. Gray says I am in shock. I am not sure about that, but I do not feel as much panic as I think might be appropriate all things considered. I am concerned by the fact that none of the others seem concerned at all after what happened. I have names, personalities and memories, but they all blend together unless I concentrate or one of them really wants to say something specific. I can not tell which memories are mine.
Hearing them is like thinking to yourself. I think they can talk to each other without me knowing though. It is them and me. Definitely not 'we', though I do try to listen to them. I am mostly in charge. They are too happy.
So, there is a clear seperation between 'them' and 'you'. 'You' have no personal memmories except those since your erruption, and 'their' memmories are tangled together.
Here is my advice to you. Make peace with 'them'. Treat them as a part of yourself, and allow 'them' to become a part of you (not to dominate you, but let their memmories become yours). If you wall them off, then your mind will become more fractured over time, resulting in a thoroughly inhuman mindstate. You've already indicated that you do not want that, when you changed your name at Alchemist's advice.
You will never be fully human again. Novas cannot go back to what they were. But you can build on your old humanity (and that of the people you joined with). Do not worry too much about internal conflict. That happens to everyone. Just try to act in ways that do not violate your nature.
If you choose to take my advice, then I recommend accepting Neil's help. He has helped me in the past, and he is a very good person.
Good luck.
