• Faction is NOT reparable.
• No forms of levitation work here.
• Evac/Succor landing location can be dangerous due to a roaming aggro mob. Tip: After evacuation, you will be facing the same way you were before. The way to the exit is east.
• Many of the creatures here are very high level, and see invisible.
• Much of the zone is underwater. This can make getting around problematic if you don't have a way to breathe underwater.
• Pathing is very odd. When someone trains from CS to WW the mobs aggroed path back through a tunnel on the opposite side of the zone this can cause even fish like seahorses to simply walk on land (although not aggro). Can also cause group wipes if in the pathing line, which isn't exact. Some natural pathing mobs can go through rocks/ground/walls although not going all the way through just clipping in.

Those with Alliance or Cinda's Charismatic Carillon can wander around the entire zone if faction is not tarnished

• To reach the Siren's Grotto zone line you must go through a small cave entrance underwater in Cobalt Scar.
• There are 3 ways to get through Siren's Grotto to Western Wastes. 1, Get a 57+ Wiz/Dru to Evacuate/Succor you through the zone. 2, Use Alliance or Cinda's Charismatic Carillon. 3, Make a run for it. You will have to pass by aggro mobs that see through invis and hit for 150+ damage. On the plus side, they're seahorses and cannot follow you out of the water, so with a bit of luck and practice, most players can make it through safely.

Those with Alliance or Cinda's Charismatic Carillon must make sure that they have not damaged their faction of the zone, you can use your faction raising spell/song/clicky to make yourself non-KOS and safely travel wherever you need to go. I believe that all of the mobs are on the same faction (Except Manatees, they will social with other mobs, but will not aggro until they are attacked/assisting another mob).
