For some unknown reason.
The two of them were attracted by another target in the visual disturbance caused by the dimension shift.
At first, Matthew was a bit confused.
This target was not placed here by him at all, so why did it have Isabelle's aura?
But he quickly realized.
Those two withered hands likely came from Isabelle, perhaps even her very essence!
"Did she leave a backdoor in the spells she granted me?"
"Once I cast this spell, it means I'm in some trouble, and she can seize the opportunity to lend me a hand?"
Before Matthew could fully feel touched.
He suddenly sensed something was wrong!
The unease stemmed from many aspects—
Firstly, if those two withered hands really belonged to Isabelle, then her current aura was too weak, too fleeting!
Secondly, his heightened insight told him that the entire arcane wilderness, no, all living beings near the astral world felt a sharp pang of grief!
Indeed.
It's just a hint, yet it's extremely intense!
