Any chance of making an oriconian palace stronghold or even in other planets that we don't have that would fit very well, the point is the storyline points an option where you say with your char to claim the resources of the dread palace (imp side) it could be made an oricon stronghold following that lines

A fair point, i preffer to think that Vaylin is somehow controling her mind

My theory is that this was a plot hole, but it may very well be possible for her to be brought back to life, but I don't think that way, Vaylin wouldn't just start following Satele Shan without her noticing anything wrong. ...
