I went into the little building next to the temple (1 map East of Burgost), I talked to the priest and he started screaming that evil was comming, then Deamonknight named "Ranthis" showed up with 2 crazy powerfull skelitens and started throwing Fireballs around as if they were snowballs! Needless to say it killed my group...

The next time I prepared but Kagen and Shar-Teal both died perminant deaths (I dont relode if I loose a character and cant reserect them, unless its my main character oviously and Minsc!...I am almost out of NPC's )

I talked to the 1 surviing priest and he said to talk to Kelddath Ormlyr (the head priest in the big temple on that map), so I did; he told me that the DeamonKnight was just a messenger and that there was a bigger and badder deamon named Lestraubimat who was going to come through a portal with an army of Fire Salamanders and other deamons! Kelddath told me that the deamon was going to arrive to the East and that I needed to hurry...

Ok, I have played through BG1 more times then I can count over the years, but this is a new one to me. What mod dose it come from?

I am going to copy & past my WieDU install information in here to show what I am using.

Anyone have any answeres?

It is new to me as well...
Maybe DarkSide or BG1 Adventures? I don't know any of them, so just guessing.
One thing is sure: not Grey Clan.
