Round 3Karnath is still by the Main Trail,
not inside the Old Graveyard. Though she is aware where her friends are, by Livonia's Monument, and does hear the singing.
------------------
Hanalee, Caden, & Bright Feather decide to take no action on their turns.
Alric picks up a stone and tosses it at the singing lady...
Lady sings her song, oblivious:
"Maria makes the mountains sound
... as the stone goes through her dress at the waist and, 'chts', bounces off what sounds like another rock, obviously the monument she's leaning on.
Like folks were up there dying"No reaction and intangible. Hmm, an illusion.
Everyone by Livonia's Monument (Passes their Passive Perception) hears a rustle by the woody rough nearest the monument (a touch greater than a dashing turn away). Turning to look, you see two very small, bipedal silhouettes, one squatting and hugging the standing one's leg, as the other cradles the squatter's head. You catch snippets of cooing, matching harmony to the song.
