These four are in a room in Bridge District. The moment you walk in, they attack. No dialogue whatsoever.

Does anyone know who they are supposed to be?

Where exactly'd you meet them?

also meet them. t'was in the eastern or north-eastern part of the bridge. I was very low level (just started) at this time. so it was a very tough battle for one of those guys summoned a fiend of some kind. must be Nabassu (Caco-fiend?). I was really impressed...

I believe this is a party of mages, if i remember correctly, that has been hired to kill you. Who exactly hired them, and how to catch them redhanded, is well, up to you. I dont remember how exactly you trigger this, perhaps it was for killing a cowled wizard? (Hmm...)

Amon-Ra

no, can't be. at that time I knew nothing 'bout cowled wizards hiring killers and stuff. it was at the very beginning of the game

I agree with Elenias -- they've "always" been there, and I haven't seen them anywhere else except that one room. It just took me some time to get there, as I was half-way expecting them to turn out being a part of some quest.

Darn, woulda had more XP if I would have killed them earlier -- this time around they didn't even have time to summon anything (summonings are good -- more XP, often more than you get for killing the mage) :)
