Kingdoms of Amalur: Reckoning

im just curious, how do you go about starting the expansions' quest lines?

also, when can they be started, exactly?

i was thinking of getting them soon... does anyone know if there is a risk of the expansions being taken off of PSN, or anything?

i recall hearing people talk about that happening if something happens to the rights to KoA, or whatever.

I can't say anything about the expansions being taken off PSN, but it should just appear in the main quest section. I purchased the expansions before ever playing the game and I had access to both of them after the tutorial was done.

Dead kel and Teeth of naros both just appear as soon as you exit the beginning area. house of valor u just do whenever u get to detyre.
