A dark forboding aura surrounds this castle and many fear to even come miles around it. It is a very large castle that is pretty fit for the ruler of it. The great dog demon Sesshoumaru lives here. Most of the time he is not here because he is either out looking for Naraku of out trying to get InuYasha's sword. He still has some guards surrounding the castle so don't think just because Sesshoumaru is not there that you can get in and life to tell the tale afterwards...
More recently the castle seems to have lessened in its intimidation, a less dark place. Greenery has suddenly appeared, lively and welcoming. Even so, the knowledge of who lives here, and the viciousness of the gaurds keeps the intimidation alive.
