Route to Enraged Lunge?

I was going to cap Enraged Lunge today, but I couldn't seem to find it.

You can't get there from Senji's Corner, cause you can't get to the big black 'pool'. The other way I figured, is the Nahpui Quarter mission? Is that true? Is that the only way to find it?

You can reach it from Senji's Corner. Took me a while to find the way, but there is a ramp that goes up, didn't see it at first because it is so dark.
I mmarked the ramp in green on the pic: http://img49.imageshack.us/my.php?im...tkeeper4bd.jpg

Thanks, will try that tonight, tomorrow and report back... thanks a bunch!
