And the reason it bestowed the Gift of Nature, even going so far as to send Rheager's soul coordinates to Matthew was to win him over.
In other words,
For the Blood River Will,
The fact that Matthew was trying to retrieve Rheager's soul from Glacia was permissible and even negligible.
Moreover, further,
If Matthew had tried to seize this opportunity to kill Glacia, the situation might have dramatically changed—
After all, Matthew was an outsider,
While Glacia was a vital minister relied on by the Blood River Will for expansion and also a significant tool for suppressing Barthor's Will.
Once he and Glacia engaged in an open confrontation in Purgatory Space,
He would inevitably be subjected to the full-scale Suppression of the Blood River Will.
It was then that the situation would become quite unpredictable.
However, this operation was an excellent opportunity for Matthew.
If he could kill Glacia in one fell swoop, the subsequent planet defense war would be much easier.
