Sorry to report that Imi’s Cradle (the patch of flowers on Telith’s Island in H8 (Exiled Lands) is no longer playing the creepy demonic whispers.
(Side question: what does haunt the Sanctuary ruins? The journey step completes, and supposedly we have listened to Telith’s ghost singing and it has given us a new perspective on Tyros the Deathbringer - but nothing actually happens, there’s no ghost, no song, no new perspective. Is there something missing, or is it something that was never implemented?)
If I remember correctly there is a lorestone on the island. i don’t remember what she says, but I guess that tells the story about what haunts the ruins.
There is indeed a lorestone - but it is the first Lemurian lorestone, and just covers the ‘You are not less than them…You can be free…When the time comes I will free you’ stuff. It is placed next to a statue of Tyros, but it provides no insight about Tyros or Telith (it doesn’t even suggest that Telith is the Witch Queen’s daughter - we find that out elsewhere). I suspect at some point it might have been intended to give a little more information linking these points together, but now the lorestone seems to be the only bit left still working.
(Picked up 8 of them yesterday - and it was the waiting around for them to respawn that got me thinking about this again 
)
