Eliza_The_Knight

Eliza was born in a small village, that was plagued by a curse: once every year, a portal opens, allowing monster to enter the world, raid the lands, and devour its inhabitants. To prevent such a fate, the tradition requires to send someone through the portal as soon as it opens, to stop the invasion.
No one of the unfortunate souls sent through the portal has ever come back, and most villagers think that they have heroically fought to protect the entrance, but the elders know that they are nothing more than a tribute to the monsters, for them to leave villagers alone
This year, Eliza is the chosen one: not knowing the truth, she is eager to protect her village, and she has been given weapons and armor. With no training, and incomplete equipment, but with enthusiasm and goodwill, she crossed the portal.
