1) You don't want to take any risks, and we leave.
2) We fail to overcome the illusion and leave.
3) We overcome the illusion:
a) Amalia gives Tarvicius the powder. Tarvicius and Adrian consume it. Adrian and Tarvicius enter. Amalia casts a veil on Adrian. Tarvicius proceeds as is. Amalia and Horus remain at the entrance and wait. Tarvicius goes ahead, Adrian slightly behind, ready to shoot anyone who attacks the mage at any moment. He also watches out for traps and other dangers. When we encounter the first sorcerer, Tarvicius tries to talk to him; if he doesn't let us pass, we kill him. (Adrian shoots him in the head. Honestly, I don't know what the best course of action is. He might let us pass initially, then attack us on the way back). When we find the second one, we do the same.
b) We are all immediately discovered and killed/captured.
c) Adrian and Tarvicius do not return within two hours (they have been captured/killed) - up to Amalia and Horus to decide.
4) Your suggested courses of action.
