Consider it seriously

At least, the invading armies hadn't reached the Blind Spiders' lair, nor had they touched Lolth's bottom line.

If this army continued to advance, they would definitely discover the Nest of their Blind Spider race.

At that point, Lolth would be in a very difficult position.

Because, deep down, Lolth wanted to surrender to that mighty existence.

After several tests, Lolth had already determined that the master of the contract scroll would be at least a demigod.

This was most likely a true escape route, and Lolth didn't want her relationship with Orion, who had sent the scroll, to become too strained.

The premise was not to touch each other's bottom lines.

Having these people stop at Shadowcrag Forest was good for both sides.
