Your history just needs a bit of a change, mostly due to how you perceive the DB training aspects. The Dark Brotherhood wouldn't have the same type of "training" as say the Jedi Academy. We wouldn't have students spending years upon years in the Shadow Academy. It would be much more short-term, with the bulk of a member's training being done at the House/Clan level. So, SA-time would probably only be a few months? Enough time to assess that someone does have force sensitivity and is able to use it at some level.
Second, we generally don't use "fake" DB members in our histories. So having a mentor as part of the DB, but never actually existed, probably shouldn't be on your wiki. Overall, I am wondering if perhaps you should focus on perhaps joining the "real" Jedi Academy and training there for a few years. Some sort of trauma may occur during that time to push you towards a darker path and into the DB itself. You can still keep your mentor, but the initial location would change. I think that would make a lot more sense for you overall, especially as you wished to focus on the healing-aspects early on --Halcyon (talk) 02:58, 7 August 2011 (UTC)
