I just woke up from a great dream.
I saw two centurions. One clothed in a golden lion mane the other had black fur of a beast. They both talked at the beginning and the end of it.
The ending sequence is them observing a huge wall/mountain with holes placed all over its surface. From within came the members of a certain group that the two legionaries knew from before.
The golden one talks about the foreseen meeting and one of the members smile with nostalgia.
