-"How does Ulysses facilitate connections between servers without an exit portal like Ogygia?" It's possible that the pathways amongst servers are already there. Remember that Nova had to basically shift Orion and Alex's path from their chosen server to Ogygia while they're still moving between servers, so it could be like simply redirecting the flow of a current that's already there. The only thing that the exit portal does is allow the projection to return its consciousness to the body unmolested.
-"How can NPCs like Thanatos and the Praetorians can jump between servers without an exit portal?" With the Praetorians it's likely Idriel. If it's revealed that she is Anima, then even better given that it's Anima's bloodline that basically has the knowledge on how to open portals and jump to worlds. With Thanatos, my current theory is that Hyas has something to do with it, as the Weapons of Atlas seem to have their own kind of teleportation. With Dione, you can teleport to where the bullet lands. With Caly, she's basically a walking portal opener. Hyas was said to be able to cut anything, so maybe it can cut the boundaries between servers and allow the wielder to walk straight into the closest one?
