Acclimatizing to Dune
Now, this was a Quest befitting of the Hall of Kadath, though it was far more dangerous than just building the new Divine Altar. Destruction was more aligned to the stereotypical image of the worshipper of the Outer Gods than building things; that would be weird even for them.
Each Divine Altar would be for surely properly guarded by the worshippers of the said God or of whatever the Divine Altar was meant to venerate. Some may even be riddled with traps and other countermeasures against the people who would want to destroy them, or they may be hidden in almost unreachable places.
Though, Samiel was confident that four of them, plus Familiars and his Undead Army that had around ten thousand Undead, would be strong enough to breach through the defenses of almost any foe that they encountered on the 10th Floor of the Tower.
