Ok, I was in a fight in DF, So i'm just gonna Copy and paste what I said to LeGenD about 2 hours ago
" The fact is, Surik had to SURVIVE on Natheema for an incredible amount of time, which is described as her having to hold the atoms of her own existence in so the planet didn't rip her apart for spare force. She also had the draining effects, because all her efforts to keep herself alive weren't enough, as is aptly described in the passages with Surik on Natheema.
This means that she had to perform incredible feats of the force, be drained, then escape off world, and the only place she could go? Kaas City, one of the strongest Dark Nexus' in the Galaxy. Noting it's almost impossible for a Jedi to feel the force there, yet alone recover and heal, as we saw when YODA had issues with his force there"

Well, seeing as it was the Emperor who made it that way, it probably is.
Kaas City is nigh impossible for Lightsiders to call upon the force in, and IIRC, Yoda was unable to call upon the force at all in the Dark Temple.
