Kingdoms of Amalur: Reckoning - The Legend of Dead Kel Community Q&A

Over on the official Kingdoms of Amalur: Reckoning forums, lead narrative designer Andrew Auseon been busy answering questions about the game's The Legend of Dead Kel, the lot of which are spread across two separate Q&A installments here and here. Let's pull out a few that stick out:
About how many hours of gameplay does this add? By Hypnosis

In our estimation, The Legend of Dead Kel adds more than ten hours of new content, and I would say that might even be a bit conservative. The expansion includes a new main quest, side quests, free-form quests, as well as a whole series of unique quests geared to the discovery and renovation of the vast Dverga keep of Gravehal. The Gravehal quests alone will keep you busy for a long time, exploring the island for ways to upgrade your estate, and for new castaways to recruit.

My question is, how the questline starts. Will there be an automatic entry in the quest log or will it start through a NPC. By Bfler

The quest line that brings you to the island of Gallows End is given automatically through the quest log, in the form of a formal call to arms from the Alfar Merchant Navy. They seek capable men and women to track and kill the notorious pirate Dead Kel and his crew of murderous Hanged Men. Of course, you will need to reach the city of Rathir before you can depart on your voyage, and then you'll need to locate a captain crazy enough to transport you to your destination.

Am I be able to get all the DLC for the PC version of the game that I bought from the game retailers since I didn't made the purchase of the game from on Origin or Steam? By StealthPhoenix

The Legend of Dead Kel will be available across all platforms. If you purchased a PC hard copy, or downloaded the game on EA's Origin service, you will be able to acquire it through Origin. If you're a Steam customer, it will be offered on Steam. And as expected, if you played Reckoning on console, you will be able to download your DLC via your console's marketplace.
