Added a few minor characters and added some lore to Sorrow Peak and its main denizen Breeze Arkaia -- it used to be a place where those whose souls had become entirely full of darkness would gather. Accordingly, there's stuff explaining more fully how the light and darkness thing works. It's mostly a background lore thing, although one of the End Tool bosses uses the light and darkness system as a means of attack.

Kind of implemented the Lensar last boss fight, although I haven't tested it yet -- I kinda forgot to do this earlier. The idea is, there's a character who's normally the 2nd-to-last boss, but he's recruitable. If you have recruited him, which is fairly difficult, you fight Lensar instead. He's far, far weaker, having only a fraction of the HP, but he (a) reads your mouse input to try to avoid being hit and (b) has the Void Slash, which functions as an overpowered version of the player's Mirror Wave, and cancels out any projectile-based attacks. Despite that, he's still not supposed to be too hard.
