Etna's Journal is a feature in Disgaea: Hour of Darkness. It can be used to unlock Etna Mode in the remakes, and provides a look at Etna's feelings and history. It later reappears in Disgaea D2: A Brighter Darkness.
How to UnlockEdit
Disgaea: Hour of Darkness 1. Examine the skull at the RosenQueen store and use the switch
2. Walk behind Laharl's throne and flick the switch.
Disgaea D2: A Brighter Darkness
1. Examine the counter of the RosenQueen store and press the switch.
2. Press the switch behind Laharl's Throne.
3. Go into the corner in the room where the Data Shop and Event Viewer are located. The player must not have Etna currently travelling around with the main character being used or use Etna to travel the base herself. If Etna is not in the travelling party, the player can enter her room.
If the player reads the newest entry each chapter, they will be rewarded with a Testament, one of the best items in the game. In the remakes, reading every entry unlocks Etna Mode in the New Game+ and grants a code which allows the player to start Etna Mode from the opening screen.
In Disgaea D2, the player will receive an Elder Spear once he/she reads all of the diary's entries.
