Ambrosia
After a few weeks of travel along the river through the valley, one would reach the Great Swamp. The swamp was home to countless mangrove trees, as well as magical beasts.
Most areas of the Great Swamp were filled with water that reached to the knees. Whereas some areas were dry but still covered in mud, making them difficult to traverse. This area was home to magical beasts such as swamp crocodiles, spike alligators, and even horned hippos.
Magi who found themselves in this sort of harsh terrain found it very difficult to move through it, much less fight their battles here.
However, conflicts were inevitable in the secret plane, especially in a place such as the Great Swamp. After all, in the center of this swamp lay a giant mangrove tree that produced special fruits.
And these fruits had great appeal to Rank 1 Magi.
