Both Weiss and Elise left their room secretly, without letting anyone know. They would not be out for too long and so early in the morning, no one should come to call for them. So them secretly going out should be fine.
But still, at least two of the maids would stay in the room for the whole duration while Weiss and Elise were out. Even if anyone came to call for Weiss, the maids would be able to send them away by giving some kind of excuse.
Both Weiss and Elise hid their presence and quickly left the mansion. Both of them were also using Fleet Footed steps so their speed was extremely fast.
The first destination that Weiss had in mind was an abandoned warehouses located not too far away from the Skepa castle.
This warehouse belonged to a merchant who used to work for the previous lord marquis. But then, it was discovered that this merchant was selling sensitive information to the marquis's enemies.
