Down below, it keeps calling it.
I guessed right!
These deathly banshees indeed have some connection with the dream realm, otherwise, they wouldn't be so sensitive to the aura of the dream realm, fiercely attacking me as soon as they catch a whiff of anything brought out from it.
This is a very unusual phenomenon. Rod initially thought it might be the black fog's malice towards the dream realm, but quickly realized that this isn't the spirit realm, and the deathly banshees aren't symbiotic with the black fog; previous monsters never exhibited this phenomenon.
From this perspective, it's very possible that the summoning source has some connection with the dream realm.
And the most common relics in the world related to the dream realm are dream shards.
The thought of this possibility made Rod's heart race wildly. If it indeed is a dream shard, then he could use his connection to the dream realm to find the source's location.
