These guys are the beastmen of Al'Taieu. The big difference is that they don't aggro, but they do link.
Each can be a different job type. They also seem to be able to change jobs mid-fight. Also, they could have Reraise on. So, after you kill one, there a chance that they will come back to life. (It's pretty freaky when you first see this.)
The version in The Grand Palace of Hu'Xzoi are generally weaker than the ones found in The Garden of Ru'Hmet. I believe that the ones by the entry way in The Grand Palace of Hu'Xzoi are DC to a level 75 player. The ones on the 2nd floor of The Garden of Ru'Hmet are IT to a level 75 player.
