Well to answer the first question. He was captured at the time he died, and since Gaul knew about how the light worked(he did basically highjack it), it’s more than likely they were destroyed similar to Cayde’s was before he died(still hurts my hunter heart.) Gaul more than likely knew how the resurrection cycle worked so he more than likely destroyed them. So no resurrection. Plus, even though he has ghosts following him, was it ever confirmed that the Speaker was a light bearer? He was never referred to as a guardian and little is actually know of his time prior to serving as the speaker as it isn’t a name, but a title.
