Aldrich's eyes swiftly scanned from side to side, analyzing the general reaction to him. Overall, there was mostly shock. He could not sense direct aggression, and that did make sense.
One factor of his undead resurrection process seemed to be that any aggression towards him, the master, was turned down to minimal levels. This was consistent with Elden World lore that typecast those that stated that necromancers made their undead into loyal servants.
Aldrich assessed the worst case scenario.
There were definite cases of undead under liches being able to rebel against them. Rare, but possible. Usually, in Aldrich's experience, it was when strong willed individuals opposed a necromancer so strongly that they could resist the control.
