It is said that Toland died while attempting to defeat Crota, and the only survivor was Eris. However, I have a feeling that he actually didn't. Maybe it looked as though he had died, and everyone including Eris thought he was dead, but he had an obsession with how the Deathsinger's liturgy works. He said that the hive survive by making themselves a part of the song, so that they will never die because they are death. Perhaps from Toland's extensive studies, he learned how to make himself part of the song, even if his body gets destroyed in the process. I'll bet some form of him still lives on, floating in the shadows. And I also think he's the voice in the E3 Taken King trailer.
