u/Exizel

In FW you have to interact with 4 obelisks to do each lord's stories and the JP fire emblem twitter account revealed that each obelisk are named after an animal(kind of like the house in 3h).

Cai has the fox's obelisk, Dietich's has the lion's obelisk, Theadora has the wolf's obelisk and Lida has the eagle's obelisk.

Just like Uka, we get only 3 souls in the main story and 6 in daily login, at first I thougth Uka got this treatment because he was the last character and Book 3 was only 2 week after his release....but that's not the case for Eugene.
