Herphah:
From levels 97 to 99... You should start to find appropriate zones on your own. I'd like to recommend three zones.
The first is the Cemetery. It is the closest one of the three. Go to the Seal of Shilen through the gatekeeper here, and find the Aden Vanguard Quartermaster. He will give you missions related with the Fallen King's Men.
The second is the Blazing Swamp. It is not far from here. Go to the Blazing Swamp through the gatekeeper and find a little unusual orc. Ask the orc about the quest Waiting for Pa'agrio. Oh, don't worry. Some orcs are quite friendly.
The last is the Pagan Temple. To get there, you should first go to the Town of Rune through the gatekeeper. Find Priestess of Light Razen inside the Pagan Temple and ask him about Triol's Movement. He will tell you what to do.
