Alright Luremaster gamers....am stuck

[Cagen the dwarven cleric]

ok Luremaster gamers......have been pounding away at every type of undead known and unknown to man, woman, elf, dwarf, and what have you. Have cleared the entire crypt, all four towers and am now at a loss. Have searched for a way to get the gate open with no luck....what am I not doing?...Oh, by the way, nice "expansion within an expansion". Like the story...

[Bald Rick]

This had me stumped for ages too.

Get the scrolls from the lower level of each of the four towers.
Put one in each of the tombs of the four knights which are in the last area you get into after you've unlocked all the doors.
The scrolls give the clue as to which of tombs they go in.
