Heart of darkness... need help

[Layne_smart]

I cant seem to figure out how to complete this mission. i have a grey key tent, a blocked blue gate by the ghost knight, which i did his quest, and a demon off to the right that just talks to me. What should i being doing next? i cant get past the blue border gate. Am i to use the alters around the Haven castles some how?
Hope there are still players around to help, thanks.

I need the same help, Layne_smart. Did you ever find out how to get past? I thought maybe sending one hero to each altar with the spell cleanse and try casting simutaneously. What's the answer?
