One of the key moments in the plot of "Veil of Darkness" is discovering the real name of Kairn. The name - contained in the pages of Agrippa the cursed book - is supposed to be chosen randomly from a long list. However, it seems that in some versions (perhaps those cracked) or on some systems the same name is "chosen" every time. For those curious, here is a list of the real names of the grim vampire: Beaulu, Bhenblod, Brcko, Dauthr, Drak, Feodor, Malachi, Seth, T'san, Yfelan.
The opening sequence says you fly your plane over a region of Romania: a valley in the middle of the Carpathians. Vlad Tepes (a.k.a. Vlad "the impaler" Dracul; count Dracula) lived and ruled in a region named Transylvania which is located in none other than Romania.
