After a morning full of sex and lust, both Yvraine and Samiel went to take a shower before they proceeded to talk about the Advancement Quests of the 10th Floor. Right now, they essentially obtain some semi-safe place of operation from where they could travel to the deserts of Sikarra and then back.
Not to mention, this shelter proved to be immune against the Arrakian sandworms below a certain stage of the Legendary Level. When they were in the underground layers of the shelter, Samiel read it was designed to resist even Intermediate Level Legendary sandworms for some time, so it could be considered one of the most secure ones.
Considering the fact of what they were researching here and storing, it was only understandable that it would be secured very well. Hopefully, this shelter was located in a position good enough, so they didn't have to travel very far from it in their search for Divine Altars of other Gods for Samiel to destroy.
"So, where do we start?"
