Secret Research is a quest in Xenoblade Chronicles. It can be received from Teelan at the Ether Plant at Eryth Sea after the events at the Mechonis Core and after completing The Missing Boy. If Fiora is in the active party, she will comment. The High Entia Emblem is required to access the Telethia Laboratory, which can be found east of the Ceremony Hall landmark. The Furious Jozan is also guarding the laboratory.
- "Collect the Telethia Research from the Telethia Laboratory in the High Entia Tomb."
- "Return to Teelan."
"You found the Telethia Research. Perhaps the Telethia will return to their original forms one day."
- Fiora: "A Telethia laboratory? That sounds like the sort of place there might be a way to do it. It's our best hope! If it's there, we should be able to find it!"
- Teelan: "I would want you to put yourself in too much danger. Naroth hated people being reckless. But it makes me happy to hear you say that."
