Ok, so I'm running the patcher today. I happen to look up because the patcher stopped for a moment to analyze a few files. I thought I saw Veeshan's Peak but wasn't sure so I searched "Veeshan" and sure enough, a lot of files popped up for Veeshan's Peak as well as Temple Veeshan.
I haven't explored everything on my monk yet but did they put in some Scars of Velious content with Ruins of Kunark? I never had EQ1 on this computer so I know its dealing with EQ2.
Veeshan's Peak is in Kunark, and always has been. A tad later, meaning once I grind till my eyes bleed, I'll give you some firsthand info on the dungeon if you want.... I raided it abit in beta.
Ok, well, lol I got banned from EQ1 shortly after Luclin came out. My memory is off. But, as I stated, Temple Veeshan did come up on my search as well.
You have to get keyed clearing the lower raid zones to enter the higher level ones. It's possible you passed by where these places are and the doors or whatever just aren't clicky to enter for you.
