I assume the quest your referring too is the "Call to arms" quest, which tells you to go to Daren, only problem is, once you click his name in the quest box, it starts to take you to the other side of the map. This is a bug, and its actually leading you to the other factions Daren. Since me trying to describe where he is through here is pointless, i suggest once your in game in Caergate, ask someone to point you to where he is because he is also on your side of the map not just the other factions side ^^
What some people don't seem to realise - and this quote is a perfect example of such a person - is that, even though the areas, quests and quest text (disregarding the faction names being mentioned) are the same in both factions, not everything is the same on both sides. Though very few, there are some NPCs who's names are different.
These are the ones I know about:
Lota (RG) and Sati (Free Knights)
Laura (RG) and Lola (Free Knights)
Nadia (RG) and Naomi (Free Knights)
Douglas (RG) and Daren (Free Knights)
I have only played RG, so I've found the differences in Caergate, and through a couple of videos on YouTube.
To make this post on-topic: I didn't realise On Hold quests could be effectively deleted. I'm pretty sure you can remove them from On Hold - correct me I'm wrong.
