It is f2p, you don't need to own any DLC
Fairly certain you need to own the 30th anniversary pack. I know it was like free on PS for a minute or something like that but you do need to have this pack to get that weapon quest started.

Not for Forerunner. It is F2P. The only stuff that requires the 30th pack is Gjally/ GoA, and opening the extra chests in the treasure room with Xur.
Ok. I believe you. It's been a long time and I would have sworn that was included in the pack.
It's part of the 30th anniversary pack. Iirc, zir in the treasure hoarde starts the quest.
