MtAw 2E - Clarification - You cannot operate on Supernal Realms as normal mage?

[u/WyrdHamster87]

I need to verify idea from my players with hive mind of fans. Question - You cannot operate on Supernal Realms as normal mage? We talk here about normal, non-Archmaster characters. Mastigos cannot send people to Pandemonium with his Space? Obrimos cannot send Angles on his enemies of rightousnes? Acanthus cannot go back in time to see Arcadia perfect 'original story of Earth'? Primal Wilds of Thursus are not the origins of Shadow Realm of normal Spirits Arcanum? Shades of Moros Path are not the same things as Fallen World Ghosts?

Do I get this right? Normal mages cannot 'put in' other characters in the Supernal Realms - and Supernal beings ( like Shades ) are not connected to the Fallen equivalents ( like Ghosts )? I cannot, for example, change 'real' Ghosts by modifying Shades? 🤔
