The Saga Quests are long quest chains that are not tied to any zone. The quest chain will usually take you to many different zones and locations and will often have group content (dungeons, raids, etc) towards the end of the questlines.
Saga questlines often give beautiful unique weapons as rewards, so even if the content is no longer relevant to you, the quests are worth doing anyway to get those lovely weapon wardrobe skins!
