Ainz finally decided to check the third notification message he had received, as he thought of it, his excitement built up.
'I wonder how big my realm of shadows would be?'
Realm of Shadows just as the name implies is a realm, to be more precise a personal dimension that is able to monitor his shadow puppets and preserve them, compared to using his sea of consciousness to store his shadow puppet, the realm of shadows had greater benefit since it doesn't place any burden on his mind when store there unlike his sea of consciousness that places a burden on his mind.
The only reason why the burden wasn't noticeable was simply because of his mana sense being strong enough to handle it, otherwise, with just the fact that the snake Queen was rank five and his original rank being peak rank 2 when he killed her, it would have crushed his mind and would have died immediately.
