The elves had a proud and glorious history. They once ruled the whole continent and many alternate dimensions. However, when a few apertures appeared and connected Abyssal Maw to the main material world, and the Demon Lords arrived with their subordinates in a scourge, bringing forth slaughter and destruction, everything became their memories.
In the war, the Elven Court finally crushed the demonic army and sealed the channels, but the elves suffered brutal casualties, too. Their population plummeted. Because of their low birth rate, they never recovered from the disaster, and they were gradually replaced by other races. They had retreated to the 'Nature's Inhabitance sss' where the few elven trees were located. One of their habitants was the Stroop forest that was one third the size of Holm.
