The activation of the Eternal Portal signified that the Buried City had now been officially reconnected to the upper world. Everyone under the Angel Faction was greatly encouraged by the news. Not only because they could freely access the Buried City and farm there after this, but the Mercenary Guild would also grant players from Angel Faction a series of Honor Quests relevant to the Underworld invasion in advance.
The first player to discover the hidden Lich's lair and return to the Mercenary Guild safely would be rewarded ten Honor Points and 1000 gold coins.
One could also gain Honor Point by accumulating kills on the Skeleton Dragons, Dark Cavaliers, or Death Knights wandering around the lair.
There was even a party specific quest. Any party that could slay a Lich would be rewarded 1000 Honor Points.
