Late in March of 1004 with the help of an adventurers group local to the region the forest resides in as well as the Elven King Lemben Abban of the kingdom of Baldai discovered that the Demon Aletto was charging the Mana Crystal of Arkantos.
They attempted to stop her but were too late. Aletto and the crystal disappeared on the 4th of April in 1004.
